Cross-Site Tracing occurs when a server will echo a request back via the Trace method, allowing an XSS attack to access to authorization headers and cookies inaccessible to JavaScript (such as cookies protected by HTTPOnly). To mitigate this attack, browsers placed limits on <code>fetch()</code> and XMLHttpRequest; however some webservers have implemented non-standard headers such as <code>X-Http-Method-Override</code> that override the HTTP method, and made this attack possible again. Thunderbird has applied the same mitigations to the use of this and similar headers. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.

Through a series of popups that reuse windowName, an attacker can cause a window to go fullscreen without the user seeing the notification prompt, resulting in potential user confusion or spoofing attacks. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.

Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allow user-assisted remote attackers to bypass the Same Origin Policy, and conduct Universal XSS (UXSS) attacks or read arbitrary files, by arranging for the presence of a crafted HTML document and a crafted shortcut file in the same local directory.

A file dialog shown while in full-screen mode could have resulted in the window remaining disabled. This vulnerability affects Firefox < 126.

Cross-site scripting (XSS) vulnerability in showdependencygraph.cgi in Bugzilla 2.x, 3.x, and 4.x before 4.2.16, 4.3.x and 4.4.x before 4.4.11, and 4.5.x and 5.0.x before 5.0.2, when a local dot configuration is used, allows remote attackers to inject arbitrary web script or HTML via a crafted bug summary.

When injecting an HTML base element, some requests would ignore the CSP's base-uri settings and accept the injected element's base instead. This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105.

Mozilla Firefox before 24.0 on Android allows attackers to bypass the Same Origin Policy, and consequently conduct cross-site scripting (XSS) attacks or obtain password or cookie information, by using a symlink in conjunction with a file: URL for a local file.

The HTML Sanitizer should have sanitized the <code>href</code> attribute of SVG <code>&lt;use&gt;</code> tags; however it incorrectly did not sanitize <code>xlink:href</code> attributes. This vulnerability affects Firefox < 102.

SVG <code>&lt;use&gt;</code> tags that referenced a same-origin document could have resulted in script execution if attacker input was sanitized via the HTML Sanitizer API. This would have required the attacker to reference a same-origin JavaScript file containing the script to be executed. This vulnerability affects Firefox < 102.

An attacker could have injected CSS into stylesheets accessible via internal URIs, such as resource:, and in doing so bypass a page's Content Security Policy. This vulnerability affects Firefox ESR < 91.11, Thunderbird < 102, Thunderbird < 91.11, and Firefox < 101.

Firefox's HTML parser did not correctly interpret HTML comment tags, resulting in an incongruity with other browsers. This could have been used to escape HTML comments on pages that put user-controlled data in them. This vulnerability affects Firefox < 101.

Cross-domain vulnerability in js/src/jsobj.cpp in Mozilla Firefox 3.x before 3.0.6 allows remote attackers to bypass the Same Origin Policy, and access the properties of an arbitrary window and conduct cross-site scripting (XSS) attacks, via vectors involving a chrome XBL method and the window.eval function.

In multipart/x-mixed-replace responses, `Content-Disposition: attachment` in the response header was not respected and did not force a download, which could allow XSS attacks. This vulnerability affects Firefox < 132, Firefox ESR < 128.4, Thunderbird < 128.4, and Thunderbird < 132.

A mutation XSS affects users calling bleach.clean with all of: svg or math in the allowed tags p or br in allowed tags style, title, noscript, script, textarea, noframes, iframe, or xmp in allowed tags the keyword argument strip_comments=False Note: none of the above tags are in the default allowed tags and strip_comments defaults to True.

Common Voice is the web app for Mozilla Common Voice, a platform for collecting speech donations in order to create public domain datasets for training voice recognition-related tools. Version 1.88.2 is vulnerable to reflected Cross-Site Scripting given that user-controlled data flows to a path expression (path of a network request). This issue may lead to reflected Cross-Site Scripting (XSS) in the context of Common Voice’s server origin. As of time of publication, it is unknown whether any patches or workarounds exist.

Scanning a QR code that contained a javascript: URL would have resulted in the Javascript being executed.

A Content-Security-Policy that blocks in-line scripts could be bypassed using an object tag to execute JavaScript in the protected document (cross-site scripting). This is a separate bypass from CVE-2019-17000.*Note: This flaw only affected Firefox 69 and was not present in earlier versions.*. This vulnerability affects Firefox < 70.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 2.0, when UTF-7 document content is rendered directly in UTF-7, allows remote attackers to inject arbitrary web script or HTML via a gopher URI that uses single quote characters to delimit a literal string within an XSS sequence, a related issue to CVE-2007-5415.

For native-to-JS bridging the app requires a unique token to be passed that ensures non-app code can't call the bridging functions. That token could leak when used for downloading files. This vulnerability affects Firefox for iOS < 26.

browser.js in Mozilla Firefox 1.5.x before 1.5.0.10 and 2.x before 2.0.0.2, and SeaMonkey before 1.0.8 uses the requesting URI to identify child windows, which allows remote attackers to conduct cross-site scripting (XSS) attacks by opening a blocked popup originating from a javascript: URI in combination with multiple frames having the same data: URI.

An object tag with a data URI did not correctly inherit the document's Content Security Policy. This allowed a CSP bypass in a cross-origin frame if the document's policy explicitly allowed data: URIs. This vulnerability affects Firefox < 70.

When a file download is specified via the `Content-Disposition` header, that directive would be ignored if the file was included via a `&lt;embed&gt;` or `&lt;object&gt;` tag, potentially making a website vulnerable to a cross-site scripting attack. This vulnerability was fixed in Firefox 140, Firefox ESR 128.12, Thunderbird 140, and Thunderbird 128.12.

Upon scanning a JavaScript URI with the QR code scanner, an attacker could have executed unauthorized scripts on the current top origin sites in the URL bar. This vulnerability affects Firefox for iOS < 123.

If a Thunderbird user replied to a crafted HTML email containing a <code>meta</code> tag, with the <code>meta</code> tag having the <code>http-equiv="refresh"</code> attribute, and the content attribute specifying an URL, then Thunderbird started a network request to that URL, regardless of the configuration to block remote content. In combination with certain other HTML elements and attributes in the email, it was possible to execute JavaScript code included in the message in the context of the message compose document. The JavaScript code was able to perform actions including, but probably not limited to, read and modify the contents of the message compose document, including the quoted original message, which could potentially contain the decrypted plaintext of encrypted data in the crafted email. The contents could then be transmitted to the network, either to the URL specified in the META refresh tag, or to a different URL, as the JavaScript code could modify the URL specified in the document. This bug doesn't affect users who have changed the default Message Body display setting to 'simple html' or 'plain text'. This vulnerability affects Thunderbird < 102.2.1 and Thunderbird < 91.13.1.
