When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65.

Memory safety bugs present in Firefox 124. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 125.

** DISPUTED ** Mozilla Firefox 1.0.7 and 1.5.0.1 allows remote attackers to cause a denial of service (crash) via an HTML tag with a large number of script action handlers such as onload and onmouseover, which triggers the crash when the user views the page source. NOTE: Red Hat has disputed this issue, suggesting that "It is likely the reporter was running the IE Tab extension," and Mozilla also confirmed that this is not an issue in Firefox itself.

Unspecified vulnerability in Mozilla Firefox allows remote attackers to execute arbitrary code via unspecified vectors involving Javascript errors. NOTE: this might be the same issue as CVE-2007-2175.

The decrease_ref_count function in libvpx in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via malformed WebM video data.

Mozilla Firefox 2.0.0.3 allows remote attackers to cause a denial of service (application crash) via a long hostname in an HREF attribute in an A element, which triggers an out-of-bounds memory access.

Style editor traffic in the Developer Tools can be routed through a service worker hosted on a third party website if a user selects error links when these tools are open. This can allow style editor information used within Developer Tools to leak cross-origin. This vulnerability affects Firefox < 58.

Proxy Auto-Config (PAC) files can specify a JavaScript function called for all URL requests with the full URL path which exposes more information than would be sent to the proxy itself in the case of HTTPS. Normally the Proxy Auto-Config file is specified by the user or machine owner and presumed to be non-malicious, but if a user has enabled Web Proxy Auto Detect (WPAD) this file can be served remotely. This vulnerability affects Firefox < 51.

If a specific sequence of actions is performed when opening a new tab, the triggering principal associated with the new tab may have been incorrect. The triggering principal is used to calculate many values, including the `Referer` and `Sec-*` headers, meaning there is the potential for incorrect security checks within the browser in addition to incorrect or misleading information sent to remote websites. *This bug only affects Firefox for Android. Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 127.

Under certain circumstances, navigating to a webpage would result in the address missing from the location URL bar, making it unclear what the URL was for the loaded webpage. This vulnerability affects Firefox for iOS < 133.

Firefox for iOS hosted Reader mode on an unauthenticated local web server, allowing another application on the same device to request arbitrary URLs and receive the response rendered with the signed-in user's cookies. This vulnerability was fixed in Firefox for iOS 151.0.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

A maliciously crafted page loaded to the sidebar through a bookmark can reference a privileged chrome window and engage in limited JavaScript operations violating cross-origin protections. This vulnerability affects Firefox < 50.

Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allow remote attackers to bypass CORS preflight protection mechanisms by leveraging (1) duplicate cache-key generation or (2) retrieval of a value from an incorrect HTTP Access-Control-* response header.

Mozilla Firefox through 27 sends HTTP Cookie headers without first validating that they have the required character-set restrictions, which allows remote attackers to conduct the equivalent of a persistent Logout CSRF attack via a crafted parameter that forces a web application to set a malformed cookie within an HTTP response.

The lifecycle of IPC Actors allows managed actors to outlive their manager actors; and the former must ensure that they are not attempting to use a dead actor they have a reference to. Such a check was omitted in WebGL, resulting in a use-after-free and a potentially exploitable crash. This vulnerability affects Firefox < 84.

Mozilla Firefox 3.0.5 allows remote attackers to trick a user into visiting an arbitrary URL via an onclick action that moves a crafted element to the current mouse position, related to a "Status Bar Obfuscation" and "Clickjacking" attack.

Mozilla Firefox 1.0.7 and earlier on Linux allows remote attackers to cause a denial of service (client crash) via an IFRAME element with a large value of the WIDTH attribute, which triggers a problem related to representation of floating-point numbers, leading to an infinite loop of widget resizes and a corresponding large number of function calls on the stack.

Use-after-free vulnerability in the DOMSVGLength class in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code by leveraging improper interaction between JavaScript code and an SVG document.

One phishing tactic on the web is to provide a link with HTTP Auth. For example 'https://www.phishingtarget.com@evil.com'. To mitigate this type of attack, Firefox will display a warning dialog; however, this warning dialog would not have been displayed if evil.com used a redirect that was cached by the browser. This vulnerability affects Firefox < 86.
