Security update for jsoup, re2j
This update for jsoup, re2j fixes the following issue:
- CVE-2026-75140: The builder copies the entire inherited namespace map on every start element, causing quadratic time and memory complexity, which attackers can exploit to trigger an OutOfMemoryError and terminate the application (bsc#1275912).
Changes for jsoup:
- Upgrade to upstream version 1.23.2
- Improvement: Improved consecutive StreamParser.selectFirst() calls during progressive parsing, so later matches are returned with their parsed contents when earlier selections had left them as parser lookahead. E.g., given
Full
Next
, selecting title and then #hit now advances the partial lookahead and returnsFull
, rather than returning an empty before its content is parsed. The updated readiness tracking follows StreamParser's normal emission order across implicit HTML structure and parser recovery. + Improvement: Improved XML parser performance and memory use for documents with many nested namespace declarations by recording namespace changes within each element scope (bsc#1275912, CVE-2026-75140). + Improvement: Improved W3CDom conversion performance for documents with many nested namespace declarations. The W3C converter now uses the same optimized namespace tracking as the XML parser. + Improvement: Improved W3CDom XML conversion to retain processing instructions, comments outside the root element, and CDATA sections, which were previously dropped or converted to text. + Improvement: DOM mutation methods, including child insertion and replacement, now reject operations that would create a cycle, such as making a node its own child or moving an ancestor beneath a descendant. + Improvement: Added Elements#before(Node), after(Node), prepend(Node), and append(Node) to match the existing HTML string methods. + Improvement: Large file-backed uploads through Connection.requestBodyStream(InputStream) now stream directly with the JDK HttpClient on Java 11+, rather than being loaded fully into memory first. + Improvement: Extended Java 11+ HTTP client reuse from requests sharing a Jsoup.newSession() to ordinary Jsoup.connect() calls, reducing transport thread and connection setup churn under sustained request loads. Sessions with custom authentication or SSL contexts continue to use their own client. + Change: Aligned the XML parser stack depth and lookups to the configured maximum, which now defaults to 512 for both HTML and XML. Use Parser#setMaxDepth(int) to configure. + Bugfix: Fixed W3CDom namespace conversion in several cases: - Namespace declarations and prefixed attributes now carry the correct namespace URI, so namespace-aware DOM lookups work as expected. - Attributes added after parsing, or included through subtree conversion, now use inherited prefix declarations. - Namespace declarations now apply regardless of attribute order, and an empty declaration shadows an inherited binding only within its scope. - With namespace awareness disabled, inherited and undeclared prefixes now receive the declarations needed for XML serialization. - Valid HTML names that are not XML QNames, such as a:b:c, are normalized. Attributes that still cannot be represented are skipped, and unrepresentable elements no longer change the surrounding tree. + Bugfix: Fixed W3CDom conversion of programmatically created or renamed elements whose names can be represented in a jsoup HTML DOM but are not valid XML names, such as 1abc. These names are now normalized (e.g. _1abc) instead of causing a NullPointerException. + Bugfix: Fixed XML doctype serialization when a system identifier contains a double quote, which could otherwise produce invalid XML. + Bugfix: XML serialization now repairs element and attribute names that start with an invalid character, rather than outputting null elements or dropping attributes. For example, an attribute named 1a is written as _1a. Additional leading underscores keep repaired attribute names unique if they conflict with another attribute. + Bugfix: Supplementary Unicode characters are now escaped correctly when serializing with non-UTF, non-ASCII output charsets such as ISO-8859-1. Previously, characters could be emitted unescaped when their low 16-bit value was representable by the configured charset, causing replacement or corruption when the output was encoded. + Bugfix: Fixed the JDK HttpClient implementation to accept responses missing a Content-Type header, matching the HttpURLConnection implementation. + Bugfix: Fixed HTTP response content-type matching to handle media types case-insensitively and recognize structured +xml suffixes, including vendor-specific media types. + Bugfix: HTTP request URL normalization now percent-encodes ASCII control characters, DEL, and embedded fragment delimiters, keeping normalized URLs valid for HTTP requests while preserving existing escapes. + Bugfix: Corrected multipart form encoding to percent-escape CR and LF in field names and filenames, matching the HTML form submission specification. Multipart file content-types containing CR or LF are now rejected with a ValidationException. + Bugfix: Aligned trailing comment placement with the HTML specification: comments after remain children of the html element, while comments after remain children of the document. + Bugfix: When using the optional re2j regular expression engine, memory allocation errors caused by complex selector patterns at match time are now normalized to a ValidationException with a Pattern complexity error message. + Bugfix: Fixed parsing of malformed SVG and MathML content so that breakout HTML tags are placed according to the HTML specification. + Bugfix: Fixed deeply nested malformed HTML parsing that could lose the document body because stack lookups did not align to the configured maximum parser depth. + Bugfix: Aligned RCDATA, RAWTEXT, and script-data parsing with the HTML specification: malformed end tags no longer consume following markup, unclosed title/textarea content stays text through EOF, and custom text tags match exact names. + Bugfix: Improved URL validation during HTTP/HTTPS URL resolution and cleaning; resolved URLs without a host are now rejected instead of being accepted based only on their scheme prefix, aligning to RFC 9110. Valid relative links and non-HTTP(S) schemes are unchanged. + Bugfix: Redirects with malformed single-slash HTTP locations now use standard URL resolution to align with browsers. + Bugfix: Template fragment parsing now handles unmatched </template> tags without throwing a ValidationException. + Bugfix: Improved source tracking for adopted formatting elements and malformed markup ending at EOF. * Changes of 1.23.1 + Improvement: Reduced retained memory when parsing with source position tracking enabled (Parser#setTrackPosition(true)). Source ranges are now stored in compact parser-owned span records instead of node and attribute user data, and Position objects are created lazily when source ranges are read. This cuts tracked DOM retained size by about 50-60% on representative benchmark documents, while keeping Node#sourceRange(), Element#endSourceRange(), and Attribute#sourceRange() behavior intact. + Improvement: Added Element#classList(), an immutable snapshot of an element's class names in attribute order. Use hasClass() when you just need to test for one class, classList() when you want to read or iterate classes without needing a mutable result, and classNames() when you want the existing mutable, deduplicated set that can be written back with classNames(Set). The class APIs now share an HTML-whitespace scanner, which also makes classNames() faster and lighter on allocation, especially when walking many elements without class names. + Improvement: Aligned HTML parser scope classification with the current HTML spec for select, foreignObject, and template. + Improvement: Simplified the HTML tree builder's scope, implied-end-tag, and special-element checks by caching parser-only options on Tag. That improves HTML parser throughput by about 10% on small inputs and up to about 30% on larger inputs in the benchmark fixtures. + Improvement: Improved HTML parser throughput stability by making hot tokeniser scan paths compile more predictably. + Improvement: fallback markup is now parsed into an inspectable DOM subtree in both the document head and body. The fallback acts as a contained parsing island, so malformed markup cannot disrupt the surrounding document structure, while normal HTML tokenization still applies within it. This also improves round-trip serialization. + Improvement: Improved redirect credential handling as a defense-in-depth measure: explicit authorization headers and request cookies are no longer forwarded across origins, reducing exposure through open redirects and aligning with HTTP guidance. Cookies managed by a CookieStore continue to follow their configured scope. + Improvement: Elements can now append their outer HTML, including their own tags, directly to an Appendable with Node#outerHtml(Appendable), without first creating a String. This complements Element#html(Appendable), which appends inner HTML only. + Improvement: Aligned CDATA tokenization with the HTML spec: CDATA syntax in HTML content is parsed as a bogus comment, while it remains supported in SVG, MathML, and XML. Also improved namespace-aware fragment parsing so SVG and MathML contexts, HTML integration points, and context-sensitive tokenizer states are handled correctly. + Improvement: When using the optional re2j regular expression engine, stack overflows caused by complex selector patterns are now normalized to a ValidationException with a Pattern complexity error message. + Bugfix: Fixed HTML parsing of mixed-case RCDATA end tags after tag-shaped text. For example, <p>Foo and <img src=x> now keep the tag-shaped content as text instead of promoting it to markup. + Bugfix: Fixed W3CDom XML conversion so plain XML elements don't serialize with the reserved XML namespace as the default namespace. Explicit XML namespaces and xml:* attributes are still preserved. + Bugfix: Preserve control characters in parsed tag names. + Bugfix: Updated HTTP redirects to follow the specification: 307 and 308 preserve the request method and content, 301 and 302 only change POST to GET, and Location is followed only for 301, 302, 303, 307, and 308 responses. Streamed request bodies are not buffered; if an automatic redirect requires replaying one, execution fails, so the caller can resend with a fresh stream. + Bugfix: Corrected the Cleaner's same-site link detection to compare hostnames rather than URL prefixes when applying rel=nofollow. + Build change: Cleaned up the Maven build for the multi-release JAR so Java 8 and Java 11+ sources compile as separate source sets. This avoids spurious Java 8 compiler warnings from newer-language overlay sources, keeps long-running parser checks behind an explicit profile, and preserves the same published artifacts and runtime behavior. + Build change: Improved parallelism and tuned timing in our integration tests, so that a full mvn clean verify drops from ~ 1m18s to ~ 21 seconds. * Changes of 1.22.2 + Improvement: Expanded and clarified NodeTraversor support for in-place DOM rewrites during NodeVisitor.head(). Current-node edits such as remove, replace, and unwrap now recover more predictably, while traversal stays within the original root subtree. This makes single-pass tree cleanup and normalization visitors easier to write, for example when unwrapping presentational elements or replacing text nodes as you walk the DOM. + Documentation: clarified that a configured Cleaner may be reused across concurrent threads, and that shared Safelist instances should not be mutated while in use. + Improvement: Updated the default HTML TagSet for current HTML elements: added dialog, search, picture, and slot; made ins, del, button, audio, video, and canvas inline by default (Tag#isInline(), aligned to phrasing content in the spec); and added readable Element.text() boundaries for controls and embedded objects via the new Tag.TextBoundary option. This improves pretty-printing and keeps normalized text from running adjacent words together. + Android (R8/ProGuard): added a rule to ignore the optional re2j dependency when not present. + Bugfix: Fixed a NodeTraversor regression in 1.21.2 where removing or replacing the current node during head() could revisit the replacement node and loop indefinitely. The traversal docs now also clarify which inserted nodes are visited in the current pass. + Bugfix: Parsing during charset sniffing no longer fails if an advisory available() call throws IOException, as seen on JDK 8 HttpURLConnection. + Bugfix: Cleaner no longer makes relative URL attributes in the input document absolute when cleaning or validating a Document. URL normalization now applies only to the cleaned output, and Safelist.isSafeAttribute() is side effect free. + Bugfix: Cleaner no longer duplicates enforced attributes when the input Document preserves attribute case. A case-variant source attribute is now replaced by the enforced attribute in the cleaned output. + Bugfix: If a per-request SOCKS proxy is configured, jsoup now avoids using the JDK HttpClient, because the JDK would silently ignore that proxy and attempt to connect directly. Those requests now fall back to the legacy HttpURLConnection transport instead, which does support SOCKS. + Bugfix: Connection.Response.streamParser() and DataUtil.streamParser(Path, ...) could fail on small inputs without a declared charset, if the initial 5 KB charset sniff fully consumed the input and closed it before the stream parse began. + Bugfix: In XML mode, doctypes with an internal subset, such as ]>, now round-trip correctly. The subset is preserved as raw text only; entities are not expanded and external DTDs are not loaded. + Build change: Migrated the integration test server from Jetty to Netty, which actively maintains support for our minimum JDK target (8). * Changes of 1.22.1 + Improvement: Added support for using the re2j regular expression engine for regex-based CSS selectors (e.g. [attr~=regex], :matches(regex)), which ensures linear-time performance for regex evaluation. This allows safer handling of arbitrary user-supplied query regexes. To enable, add the com.google.re2j dependency to your classpath, e.g.: com.google.re2j re2j 1.8 (If you already have that dependency in your classpath, but you want to keep using the Java regex engine, you can disable re2j via System.setProperty("jsoup.useRe2j", "false").) You can confirm that the re2j engine has been enabled correctly by calling Regex.usingRe2j(). + Improvement: Added an instance method Parser#unescape(String, boolean) that unescapes HTML entities using the parser's configuration (e.g. to support error tracking), complementing the existing static utility Parser.unescapeEntities(String, boolean). + Improvement: Added a configurable maximum parser depth (to limit the number of open elements on stack) to both HTML and XML parsers. The HTML parser now defaults to a depth of 512 to match browser behavior, and protect against unbounded stack growth, while the XML parser keeps unlimited depth by default, but can opt into a limit via Parser.setMaxDepth(). + Build: added CI coverage for JDK 25. + Build: added a CI fuzzer for contextual fragment parsing (in addition to existing full body HTML and XML fuzzers). + Change: Set a removal schedule of jsoup 1.24.1 for previously deprecated APIs. + Bugfix: Previously cached child Elements of an Element were not correctly invalidated in Node#replaceWith(Node), which could lead to incorrect results when subsequently calling Element#children(). + Bugfix: Attribute selector values are now compared literally without trimming. Previously, jsoup trimmed whitespace from selector values and from element attribute values, which could cause mismatches with browser behavior (e.g. [attr=" foo "]). Now matches align with the CSS specification and browser engines. + Bugfix: When using the JDK HttpClient, any system default proxy (ProxySelector.getDefault()) was ignored. Now, the system proxy is used if a per-request proxy is not set. + Bugfix: A ValidationException could be thrown in the adoption agency algorithm with particularly broken input. Now logged as a parse error. + Bugfix: Null characters in the HTML body were not consistently removed; and in foreign content were not correctly replaced. + Bugfix: An IndexOutOfBoundsException could be thrown when parsing a body fragment with crafted input. Now logged as a parse error. + Bugfix: When using StructuralEvaluators (e.g., a parent child selector) across many retained threads, their memoized results could also be retained, increasing memory use. These results are now cleared immediately after use, reducing overall memory consumption. + Bugfix: Cloning a Parser now preserves any custom TagSet applied to the parser. + Bugfix: Custom tags marked as Tag.Void now parse and serialize like the built-in void elements: they no longer consume following content, and the XML serializer emits the expected self-closing form. + Bugfix: Theelement is once again classified as an inline tag (Tag.isBlock() == false), matching common developer expectations and its role as phrasing content in HTML, while pretty-printing and text extraction continue to treat it as a line break in the rendered output. + Bugfix: Fixed an intermittent truncation issue when fetching and parsing remote documents via Jsoup.connect(url).get(). On responses without a charset header, the initial charset sniff could sometimes (depending on buffering / available() behavior) be mistaken for end-of-stream and a partial parse reused, dropping trailing content. + Bugfix: TagSet copies no longer mutate their template during lazy lookups, preventing cross-thread ConcurrentModificationException when parsing with shared sessions. + Bugfix: Fixed parsing of foreignObject content nested within a
, which could incorrectly move the HTML subtree
outside the SVG.
+ Change: Deprecated internal helper
org.jsoup.internal.Functions (for removal in v1.23.1). This
was previously used to support older Android API levels
without full java.util.function coverage; jsoup now requires
core library desugaring so this indirection is no longer
necessary.
* Changes of 1.21.2
+ Change: Deprecated internal (yet visible) methods
Normalizer#normalize(String, bool) and
Attribute#shouldCollapseAttribute(Document.OutputSettings).
These will be removed in a future version.
+ Change: Deprecated
Connection#sslSocketFactory(SSLSocketFactory) in favor of the
new Connection#sslContext(SSLContext). Using sslSocketFactory
will force the use of the legacy HttpUrlConnection
implementation, which does not support HTTP/2.
+ Improvement: When pretty-printing, if there are consecutive
text nodes (via DOM manipulation), the non-significant
whitespace between them will be collapsed.
+ Improvement: Updated Connection.Response#statusMessage() to
return a simple loggable string message (e.g. "OK") when using
the HttpClient implementation, which doesn't otherwise return
any server-set status message.
+ Improvement: Attributes#size() and Attributes#isEmpty() now
exclude any internal attributes (such as user data) from their
count. This aligns with the attributes' serialized output and
iterator.
+ Improvement: Added Connection#sslContext(SSLContext) to
provide a custom SSL (TLS) context to requests, supporting
both the HttpClient and the legacy HttUrlConnection
implementations.
+ Improvement: Performance optimizations for DOM manipulation
methods including when repeatedly removing an element's first
child (element.child(0).remove()), and when using
Parser#parseBodyFragement() to parse a large number of direct
children.
+ Bugfix: When parsing from an InputStream and a multibyte
character happened to straddle a buffer boundary, the stream
would not be completely read.
+ Bugfix: In NodeTraversor, if a last child element was removed
during the head() call, the parent would be visited twice.
+ Bugfix: Cloning an Element that has an Attributes object would
add an empty internal user-data attribute to that clone, which
would cause unexpected results for Attributes#size() and
Attributes#isEmpty().
+ Bugfix: In a multithreaded application where multiple threads
are calling Element#children() on the same element
concurrently, a race condition could happen when the method
was generating the internal child element cache (a filtered
view of its child nodes). Since concurrent reads of DOM
objects should be threadsafe without external synchronization,
this method has been updated to execute atomically.
+ Bugfix: When parsing HTML with svg:script elements in SVG
elements, don't enter the Text insertion mode, but continue to
parse as foreign content. Otherwise, misnested HTML could then
cause an IndexOutOfBoundsException.
+ Bugfix: Malformed HTML could throw an
IndexOutOfBoundsException during the adoption agency.
* Changes of 1.21.1
+ Change: Removed previously deprecated methods.
+ Change: Deprecated the :matchText pseduo-selector due to its
side effects on the DOM; use the new ::textnode selector and
the Element#selectNodes(String css, Class type) method
instead.
+ Change: Deprecated Connection.Response#bufferUp() in lieu of
Connection.Response#readFully() which can throw a checked
IOException.
+ Change: Deprecated internal methods
Validate#ensureNotNull(Object) (replaced by typed
Validate#expectNotNull(T)); protected HTML appenders from
Attribute and Node.
+ Change: If you happen to be using any of the deprecated
methods, please take the opportunity now to migrate away from
them, as they will be removed in a future release.
+ Improvement: Enhanced the Selector to support direct matching
against nodes such as comments and text nodes. For example,
you can now find an element that follows a specific comment:
::comment:contains(prices) + p will select p elements
immediately after a comment. Supported types
include ::node, ::leafnode, ::comment, ::text, ::data, and
::cdata. Node contextual selectors like ::node:contains(text),
:matches(regex), and :blank are also supported. Introduced
Element#selectNodes(String css) and Element#selectNodes(String
css, Class nodeType) for direct node selection.
+ Improvement: Added TagSet#onNewTag(Consumer customizer):
register a callback that's invoked for each new or cloned Tag
when it's inserted into the set. Enables dynamic tweaks of tag
options (for example, marking all custom tags as self-closing,
or everything in a given namespace as preserving whitespace).
+ Improvement: Made TokenQueue and CharacterReader
autocloseable, to ensure that they will release their buffers
back to the buffer pool, for later reuse.
+ Improvement: Added Selector#evaluatorOf(String css), as a
clearer way to obtain an Evaluator from a CSS query. An alias
of QueryParser.parse(String css).
+ Improvement: Custom tags (defined via the TagSet) in a foreign
namespace (e.g. SVG) can be configured to parse as data tags.
+ Improvement: Added NodeVisitor#traverse(Node) to simplify node
traversal calls (vs. importing NodeTraversor).
+ Improvement: Updated the default user-agent string to improve
compatibility.
+ Improvement: The HTML parser now allows the specific text-data
type (Data, RcData) to be customized for known tags.
(Previously, that was only supported on custom tags.)
+ Improvement: Added Connection.Response#readFully() as a
replacement for Connection.Response#bufferUp() with an
explicit IOException. Similarly, added
Connection.Response#readBody() over
Connection.Response#body(). Deprecated
Connection.Response#bufferUp().
+ Improvement: When serializing HTML, the < and > characters are
now escaped in attributes. This helps prevent a class of
mutation XSS attacks.
+ Improvement: Changed Connection to prefer using the JDK's
HttpClient over HttpUrlConnection, if available, to enable
HTTP/2 support by default. Users can disable via
-Djsoup.useHttpClient=false.
+ Bugfix: The contents of a script in a svg foreign context
should be parsed as script data, not text.
+ Bugfix: Tag#isFormSubmittable() was updating the Tag's
options.
+ Bugfix: The HTML pretty-printer would incorrectly trim
whitespace when text followed an inline element in a block
element.
+ Bugfix: Custom tags with hyphens or other non-letter
characters in their names now work correctly as Data or RcData
tags. Their closing tags are now tokenized properly.
+ Bugfix: When cloning an Element, the clone would retain the
source's cached child Element list (if any), which could lead
to incorrect results when modifying the clone's child
elements.
* Changes of 1.20.1
+ Change: To better follow the HTML5 spec and current browsers,
the HTML parser no longer allows self-closing tags ()
to close HTML elements by default. Foreign content (SVG,
MathML), and content parsed with the XML parser, still
supports self-closing tags. If you need specific HTML tags to
support self-closing, you can register a custom tag via the
TagSet configured in Parser.tagSet(), using
Tag#set(Tag.SelfClose). Standard void tags (such as ,
, etc.) continue to behave as usual and are not affected
by this change.
+ Change: The following internal components have been
deprecated. If you do happen to be using any of these, please
take the opportunity now to migrate away from them, as they
will be removed in jsoup 1.21.1.
- ChangeNotifyingArrayList,
Document.updateMetaCharsetElement(),
Document.updateMetaCharsetElement(boolean),
HtmlTreeBuilder.isContentForTagData(String),
Parser.isContentForTagData(String),
Parser.setTreeBuilder(TreeBuilder), Tag.formatAsBlock(),
Tag.isFormListed(), TokenQueue.addFirst(String),
TokenQueue.chompTo(String),
TokenQueue.chompToIgnoreCase(String),
TokenQueue.consumeToIgnoreCase(String),
TokenQueue.consumeWord(), TokenQueue.matchesAny(String...)
+ Improvement: Rebuilt the HTML pretty-printer, to simplify and
consolidate the implementation, improve consistency, support
custom Tags, and provide a cleaner path for ongoing
improvements. The specific HTML produced by the pretty-printer
may be different from previous versions.
+ Improvement: Added the ability to define custom tags, and to
modify properties of known tags, via the TagSet tag
collection. Their properties can impact both the parse and how
content is serialized (output as HTML or XML).
+ Improvement: Element.cssSelector() will prefer to return
shorter selectors by using ancestor IDs when available and
unique. E.g. #id > div > p instead of html > body > div > div
> p.
+ Improvement: Added Elements.deselect(int index),
Elements.deselect(Object o), and Elements.deselectAll()
methods to remove elements from the Elements list without
removing them from the underlying DOM. Also added
Elements.asList() method to get a modifiable list of elements
without affecting the DOM. (Individual Elements remain linked
to the DOM.)
+ Improvement: Added support for sending a request body from an
InputStream with Connection.requestBodyStream(InputStream
stream).
+ Improvement: The XML parser now supports scoped xmlns: prefix
namespace declarations, and applies the correct namespace to
Tags and Attributes. Also, added Tag#prefix(),
Tag#localName(), Attribute#prefix(), Attribute#localName(),
and Attribute#namespace() to retrieve these.
+ Improvement: CSS identifiers are now escaped and unescaped
correctly to the CSS spec. Element#cssSelector() will emit
appropriately escaped selectors, and the QueryParser supports
those. Added Selector.escapeCssIdentifier() and `
Selector.unescapeCssIdentifier().
+ Improvement: Refactored the CSS QueryParser into a clearer
recursive descent parser.
+ Improvement: CSS selectors with consecutive combinators (e.g.
div >> p) will throw an explicit parse exception.
+ Performance: reduced the shallow size of an Element from 40 to
32 bytes, and the NodeList from 32 to 24.
+ Performance: reduced GC load of new StringBuilders when
tokenizing input HTML.
+ Improvement: Made Parser instances threadsafe, so that
inadvertent use of the same instance across threads will not
lead to errors. For actual concurrency, use
Parser#newInstance() per thread.
+ Bugfix: Element names containing characters invalid in XML are
now normalized to valid XML names when serializing.
+ Bugfix: When serializing to XML, characters that are invalid
in XML 1.0 should be removed (not encoded).
+ Bugfix: When converting a Document to the W3C DOM in W3CDom,
elements with an attribute in an undeclared namespace now get
a declaration of xmlns:prefix="undefined". This allows
subsequent serialization to XML via W3CDom.asString() to
succeed.
+ Bugfix: The StreamParser could emit the final elements of a
document twice, due to how onNodeCompleted was fired when
closing out the stack.
+ Bugfix: When parsing with the XML parser and error tracking
enabled, the trailing ? in would
incorrectly emit an error.
+ Bugfix: Calling Element#cssSelector() on an element with
combining characters in the class or ID now produces the
correct output.
* Changes of 1.19.1
+ Change: Added support for http/2 requests in Jsoup.connect(),
when running on Java 11+, via the Java HttpClient
implementation.
- In this version of jsoup, the default is to make requests
via the HttpUrlConnection implementation: use
System.setProperty("jsoup.useHttpClient", "true"); to enable
making requests via the HttpClient (if available), which
will enable http/2 support. This will become the default in
a later version of jsoup, so now is a good time to validate
it.
- If you are repackaging the jsoup jar in your deployment
(i.e. creating a shaded- or a fat-jar), make sure to specify
that as a Multi-Release JAR.
- If the HttpClient impl is not available in your JRE,
requests will continue to be made via HttpURLConnection (in
http/1.1 mode).
+ Change: Updated the minimum Android API Level validation from
10 to 21. As with previous jsoup versions, Android developers
need to enable core library desugaring. The minimum Java
version remains Java 8.
+ Change: Removed previously deprecated class:
org.jsoup.UncheckedIOException (replace with
java.io.UncheckedIOException); moved previously deprecated
method Element Element#forEach(Consumer) to void
Element#forEach(Consumer()).
+ Change: Deprecated the methods
Document#updateMetaCharsetElement(boolean) and
Document#updateMetaCharsetElement(), as the setting had no
effect. When Document#charset(Charset) is called, the
document's meta charset or XML encoding instruction is always
set.
+ Improvement: When cleaning HTML with a Safelist that preserves
relative links, the isValid() method will now consider these
links valid. Additionally, the enforced attribute rel=nofollow
will only be added to external links when configured in the
safelist.
+ Improvement: Added Element#selectStream(String query) and
Element#selectStream(Evaluator) methods, that return a Stream
of matching elements. Elements are evaluated and returned as
they are found, and the stream can be terminated early.
+ Improvement: Element objects now implement Iterable, enabling
them to be used in enhanced for loops.
+ Improvement: Added support for fragment parsing from a Reader
via Parser#parseFragmentInput(Reader, Element, String).
+ Improvement: Reintroduced CLI executable examples, in
jsoup-examples.jar.
+ Improvement: Optimized performance of selectors like #id
.class (and other similar descendant queries) by around 4.6x,
by better balancing the Ancestor evaluator's cost function in
the query planner.
+ Improvement: Removed the legacy parsing rules for
tags, which would autovivify a form element with labels. This
is no longer in the spec.
+ Improvement: Added Elements.selectFirst(String cssQuery) and
Elements.expectFirst(String cssQuery), to select the first
matching element from an Elements list.
+ Improvement: When parsing with the XML parser, XML
Declarations and Processing Instructions are directly handled,
vs bouncing through the HTML parser's bogus comment handler.
Serialization for non-doctype declarations no longer end with
a spurious !.
+ Improvement: When converting parsed HTML to XML or the W3C
DOM, element names containing < are normalized to _ to ensure
valid XML. For example, becomes , as XML
does not allow < in element names, but HTML5 does.
+ Improvement: Reimplemented the HTML5 Adoption Agency Algorithm
to the current spec. This handles mis-nested formating /
structural elements.
+ Bugfix: If an element has an ; in an attribute name, it could
not be converted to a W3C DOM element, and so subsequent XPath
queries could miss that element. Now, the attribute name is
more completely normalized.
+ Bugfix: For backwards compatibility, reverted the internal
attribute key for doctype names to "name".
+ Bugfix: In Connection, skip cookies that have no name, rather
than throwing a validation exception.
+ Bugfix: When running on JDK 1.8, the error
java.lang.NoSuchMethodError:
java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer; could be
thrown when calling Response#body() after parsing from a URL
and the buffer size was exceeded.
+ Bugfix: For backwards compatibility, allow null InputStream
inputs to Jsoup.parse(InputStream stream, ...), by returning
an empty Document.
+ Bugfix: A template tag containing an li within an open li
would be parsed incorrectly, as it was not recognized as a
"special" tag (which have additional processing rules). Also,
added the SVG and MathML namespace tags to the list of special
tags.
+ Bugfix: A template tag containing a button within an open
button would be parsed incorrectly, as the "in button scope"
check was not aware of the template element. Corrected other
instances including MathML and SVG elements, also.
+ Bugfix: An :nth-child selector with a negative digit-less
step, such as :nth-child(-n+2), would be parsed incorrectly as
a positive step, and so would not match as expected.
+ Bugfix: Calling doc.charset(charset) on an empty XML document
would throw an IndexOutOfBoundsException.
+ Bugfix: Fixed a memory leak when reusing a nested
StructuralEvaluator (e.g., a selector ancestor chain like A B
C) by ensuring cache reset calls cascade to inner members.
+ Bugfix: Concurrent calls to doc.clone().append(html) were not
supported. When a document was cloned, its Parser was not
cloned but was a shallow copy of the original parser.
* Changes of 1.18.3
+ Bugfix: When serializing to XML, attribute names containing -,
., or digits were incorrectly marked as invalid and removed.
* Changes of 1.18.2
+ Improvement: Optimized the throughput and memory use
throughout the input read and parse flows, with heap
allocations and GC down between -6% and -89%, and throughput
improved up to +143% for small inputs. Most inputs sizes will
see throughput increases of ~ 20%. These performance
improvements come through recycling the backing byte[] and
char[] arrays used to read and parse the input.
+ Improvement: Speed optimized html() and Entities.escape() when
the input contains UTF characters in a supplementary plane, by
around 49%.
+ Improvement: The form associated elements returned by
FormElement.elements() now reflect changes made to the DOM,
subsequently to the original parse.
+ Improvement: In the TreeBuilder, the onNodeInserted() and
onNodeClosed() events are now also fired for the outermost /
root Document node. This enables source position tracking on
the Document node (which was previously unset). And it also
enables the node traversor to see the outer Document node.
+ Improvement: Selected Elements can now be position swapped
inline using Elements#set().
+ Bugfix: Element.cssSelector() would fail if the element's
class contained a * character.
+ Bugfix: When tracking source ranges, a text node following an
invalid self-closing element may be left untracked.
+ Bugfix: When a document has no doctype, or a doctype not named
html, it should be parsed in Quirks Mode.
+ Bugfix: With a selector like div:has(span + a), the has()
component was not working correctly, as the inner combining
query caused the evaluator to match those against the outer's
siblings, not children.
+ Bugfix: A selector query that included multiple :has()
components in a nested :has() might incorrectly execute.
+ Bugfix: When cookie names in a response are duplicated, the
simple view of cookies available via
Connection.Response#cookies() will provide the last one set.
Generally it is better to use the Jsoup.newSession method to
maintain a cookie jar, as that applies appropriate path
selection on cookies when making requests.
+ Bugfix: When parsing named HTML entities, base entities should
resolve if they are a prefix of the input token (and not in an
attribute).
+ Bugfix: Fixed incorrect tracking of source ranges for
attributes merged from late-occurring elements that were
implicitly created (html or body).
+ Bugfix: Follow the current HTML specification in the tokenizer
to allow < as part of a tag name, instead of emitting it as a
character node.
+ Bugfix: Similarly, allow a < as the start of an attribute
name, vs creating a new element. The previous behavior was
intended to parse closer to what we anticipated the author's
intent to be, but that does not align to the spec or to how
browsers behave.
* Changes of 1.18.1
+ Improvement: Stream Parser: A StreamParser provides a
progressive parse of its input. For URL requests, available
via Connection.Response.streamParser(). As each Element is
completed, it is emitted via a Stream or Iterator interface.
Elements returned will be complete with all their children,
and an (empty) next sibling, if applicable. Elements (or their
children) may be removed from the DOM during the parse, for
e.g. to conserve memory, providing a mechanism to parse an
input document that would otherwise be too large to fit into
memory, yet still providing a DOM interface to the document
and its elements. Additionally, the parser provides a
selectFirst(String query) / selectNext(String query), which
will run the parser until a hit is found, at which point the
parse is suspended. It can be resumed via another select()
call, or via the stream() or iterator() methods.
+ Improvement: Download Progress: added a Response Progress
event interface, which reports progress and URLs are
downloaded (and parsed). Set via
Connection.onResponseProgress(). Supported on both a session
and a single connection level.
+ Improvement: Added Path accepting parse methods:
Jsoup.parse(Path), Jsoup.parse(path, charsetName, baseUri,
parser), etc.
+ Improvement: Updated the button tag configuration to include a
space between multiple button elements in the Element.text()
method.
+ Improvement: Added support for the ns|* all elements in
namespace Selector.
+ Improvement: When normalising attribute names during
serialization, invalid characters are now replaced with _, vs
being stripped. This should make the process clearer, and
generally prevent an invalid attribute name being coerced
unexpectedly.
+ Change: Removed previously deprecated internal classes and
methods.
+ Build change: the built jar's OSGi manifest no longer imports
itself.
+ Bugfix: When tracking source positions, if the first node was
a TextNode, its position was incorrectly set to -1.
+ Bugfix: When connecting (or redirecting) to URLs with
characters such as {, } in the path, a Malformed URL exception
would be thrown (if in development), or the URL might
otherwise not be escaped correctly (if in production). The URL
encoding process has been improved to handle these characters
correctly.
+ Bugfix: When using W3CDom with a custom output Document, a
Null Pointer Exception would be thrown.
+ Bugfix: The :has() selector did not match correctly when using
sibling combinators (like e.g.: h1:has(+h2)).
+ Bugfix: The :empty selector incorrectly matched elements that
started with a blank text node and were followed by non-empty
nodes, due to an incorrect short-circuit.
+ Bugfix: Element.cssSelector() would fail with "Did not find
balanced marker" when building a selector for elements that
had a ( or [ in their class names. And selectors with those
characters escaped would not match as expected.
+ Bugfix: Updated Entities.escape(string) to make the escaped
text suitable for both text nodes and attributes (previously
was only for text nodes). This does not impact the output of
Element.html() which correctly applies a minimal escape
depending on if the use will be for text data or in a quoted
attribute.
+ Fuzz: a Stack Overflow exception could occur when resolving a
crafted URL, in the normalizing regex.
* Changes of 1.17.2
+ Improvement: Attribute object accessors: Added
Element.attribute(String) and Attributes.attribute(String) to
more simply obtain an Attribute object.
+ Improvement: Attribute source tracking: If source tracking is
on, and an Attribute's key is changed (via
Attribute.setKey(String)), the source range is now still
tracked in Attribute.sourceRange().
+ Improvement: Wildcard attribute selector: Added support for
the [*] element with any attribute selector. And also restored
support for selecting by an empty attribute name prefix ([^]).
+ Bugfix: Mixed-cased source position: When tracking the source
position of attributes, if the source attribute name was
mix-cased but the parser was lower-case normalizing attribute
names, the source position for that attribute was not tracked
+ Bugfix: Source position NPE: When tracking the source position
of a body fragment parse, a null pointer exception was thrown.
+ Bugfix: Multi-point emoji entity: A multi-point encoded emoji
entity may be incorrectly decoded to the replacement character
+ Bugfix: Selector sub-expressions: (Regression) in a selector
like parent [attr=va], other, the , OR was binding to
[attr=va] instead of parent [attr=va], causing incorrect
selections. The fix includes a EvaluatorDebug class that
generates a sexpr to represent the query, allowing simpler and
more thorough query parse tests.
+ Bugfix: XML CData output: When generating XML-syntax output
from parsed HTML, script nodes containing (pseudo) CData
sections would have an extraneous CData section added, causing
script execution errors. Now, the data content is emitted in a
HTML/XML/XHTML polyglot format, if the data is not already
within a CData section.
+ Bugfix: Thread safety: The :has evaluator held a
non-thread-safe Iterator, and so if an Evaluator object was
shared across multiple concurrent threads, a NoSuchElement
exception may be thrown, and the selected results may be
incorrect. Now, the iterator object is a thread-local.
* Changes of 1.17.1
+ Improvement: in Jsoup.connect(), added support for
request-level authentication, supporting authentication to
proxies and to servers.
+ Improvement: in the Elements list, added direct support for
`#set(index, element)`, `#remove(index)`, `#remove(object)`,
`#clear()`, `#removeAll(collection)`,
`#retainAll(collection)`, `#removeIf(filter)`,
`#replaceAll(operator)`. These methods update the original
DOM, as well as the Elements list.
+ Improvement: added the NodeIterator class, to efficiently
traverse a node tree using the Iterator interface. And
added Stream Element#stream() and Node#nodeStream() methods,
to enable fluent composable stream pipelines of node
traversals.
+ Improvement: when changing the OutputSettings syntax to XML,
the xhtml EscapeMode is automatically set by default.
+ Improvement: added the `:is(selector list)` pseudo-selector,
which finds elements that match any of the selectors in the
selector list. Useful for making large ORed selectors more
readable.
+ Improvement: repackaged the library with native (vs automatic)
JPMS module support.
+ Improvement: better fidelity of source positions when tracking
is enabled. And implicitly created or closed elements are
tracked and detectable via Range.isImplicit().
+ Improvement: when source tracking is enabled, the source
position for attribute names and values is now available.
Attribute#sourceRange() provides the ranges.
+ Improvement: when running concurrently under Java 21+ Virtual
Threads, virtual threads could be pinned to their carrier
platform thread when parsing an input stream. To improve
performance, particularly when parsing fetched URLs, the
internal ConstrainableInputStream has been replaced by
ControllableInputStream, which avoids the locking which caused
that pinning.
+ Improvement: in Jsoup.Connect, allow any XML mimetype as a
supported mimetype. Was previously limited to
`{application|text}/xml`. This enables for e.g. fetching SVGs
with a image/svg+xml mimetype, without having to disable
mimetype validation.
+ Bugfix: when outputting with XML syntax, HTML elements that
were parsed as data nodes (

Описание
jsoup through 1.23.2, fixed in commit 862ba2f, contains an uncontrolled resource consumption vulnerability in XmlTreeBuilder that allows remote attackers to exhaust JVM heap memory by supplying a deeply nested XML document with uniquely-namespaced elements. The builder copies the entire inherited namespace map on every start element, causing quadratic time and memory complexity, which attackers can exploit to trigger an OutOfMemoryError and terminate the application.
