WordPress — свободно распространяемая система управления содержимым сайта с открытым исходным кодом.

Before version 4.8.2, WordPress was susceptible to a Cross-Site Scripting attack in the link modal via a javascript: or data: URL.

Before version 4.8.2, WordPress allowed a Directory Traversal attack in the Customizer component via a crafted theme filename.

Before version 4.8.2, WordPress was susceptible to an open redirect attack in wp-admin/edit-tag-form.php and wp-admin/user-edit.php.

Before version 4.8.2, WordPress mishandled % characters and additional placeholder values in $wpdb->prepare, and thus did not properly address the possibility of plugins and themes enabling SQL injection attacks.

Before version 4.8.2, WordPress was vulnerable to cross-site scripting in oEmbed discovery.

Before version 4.8.2, WordPress was vulnerable to a cross-site scripting attack via shortcodes in the TinyMCE visual editor.

WordPress through 4.8.2 uses a weak MD5-based password hashing algorithm, which makes it easier for attackers to determine cleartext values by leveraging access to the hash values. NOTE: the approach to changing this may not be fully compatible with certain use cases, such as migration of a WordPress site from a web host that uses a recent PHP version to a different web host that uses PHP 5.2. These use cases are plausible (but very unlikely) based on statistics showing widespread deployment of WordPress with obsolete PHP versions.

Multiple cross-site scripting (XSS) vulnerabilities in WordPress before 3.0.5 allow remote authenticated users to inject arbitrary web script or HTML via vectors related to (1) the Quick/Bulk Edit title (aka post title or post_title), (2) post_status, (3) comment_status, (4) ping_status, and (5) escaping of tags within the tags meta box.

SQL injection vulnerability in the do_trackbacks function in wp-includes/comment.php in WordPress before 3.0.2 allows remote authenticated users to execute arbitrary SQL commands via the Send Trackbacks field.

Multiple cross-site scripting (XSS) vulnerabilities in KSES, as used in WordPress before 3.0.4, allow remote attackers to inject arbitrary web script or HTML via vectors related to (1) the & (ampersand) character, (2) the case of an attribute name, (3) a padded entity, and (4) an entity that is not in normalized form.
