Cross-site scripting (XSS) vulnerability in Adobe Flash Player before 10.3.183.15 and 11.x before 11.1.102.62 on Windows, Mac OS X, Linux, and Solaris; before 11.1.111.6 on Android 2.x and 3.x; and before 11.1.115.6 on Android 4.x allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, aka "Universal XSS (UXSS)," as exploited in the wild in February 2012.

JetBrains YouTrack versions before 2019.2.53938 had a possible XSS through issue attachments when using the Firefox browser.

Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site.

An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the `resource://devtools` origin. This could allow them to access cross-origin JSON content. This access is limited to "same site" documents by the Site Isolation feature on desktop clients, but full cross-origin access is possible on Android versions. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Firefox ESR < 115.16, Thunderbird < 128.3, and Thunderbird < 131.

Insufficient data validation in Omnibox in Google Chrome on Android prior to 129.0.6668.58 allowed a remote attacker who convinced a user to engage in specific UI gestures to inject arbitrary scripts or HTML (XSS) via a crafted set of UI gestures. (Chromium security severity: Medium)

Firefox adds web-compatibility shims in place of some tracking scripts blocked by Enhanced Tracking Protection. On a site protected by Content Security Policy in "strict-dynamic" mode, an attacker able to inject an HTML element could have used a DOM Clobbering attack on some of the shims and achieved XSS, bypassing the CSP strict-dynamic protection. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, and Firefox ESR < 128.1.

The default webcal: protocol handler will load a web site vulnerable to cross-site scripting (XSS) attacks. This default was left in place as a legacy feature and has now been removed. *Note: this issue only affects users with an account on the vulnerable service. Other users are unaffected.*. This vulnerability affects Firefox < 67.

Some HTML elements, such as &lt;title&gt; and &lt;textarea&gt;, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.

Failure to correctly handle null bytes when processing HTML entities resulted in Firefox incorrectly parsing these entities. This could have led to HTML comment text being treated as HTML which could have led to XSS in a web application under certain conditions. It could have also led to HTML entities being masked from filters - enabling the use of entities to mask the actual characters of interest from filters. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.

Due to an error while parsing page content, it is possible for properly sanitized user input to be misinterpreted and lead to XSS hazards on web sites in certain circumstances. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.

Cross-site scripting (XSS) vulnerability in the Admin Control Center in Sentinel HASP Run-time Environment 5.95 and earlier in SafeNet Sentinel HASP (formerly Aladdin HASP SRM) run-time installer before 6.x and SDK before 5.11, as used in 7 Technologies (7T) IGSS 7 and other products, when Firefox 2.0 is used, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors that trigger write access to a configuration file.

Multiple cross-site scripting (XSS) vulnerabilities in Bugzilla 2.x and 3.x before 3.4.13, 3.5.x and 3.6.x before 3.6.7, 3.7.x and 4.0.x before 4.0.3, and 4.1.x through 4.1.3, when debug mode is used, allow remote attackers to inject arbitrary web script or HTML via vectors involving a (1) tabular report, (2) graphical report, or (3) new chart.

Insufficient data validation in HTML parser in Google Chrome prior to 67.0.3396.62 allowed a remote attacker to bypass same origin policy via a crafted HTML page.

Collabora Online is a collaborative online office suite based on LibreOffice technology. In the mobile (Android/iOS) device variants of Collabora Online it was possible to inject JavaScript via url encoded values in links contained in documents. Since the Android JavaScript interface allows access to internal functions, the likelihood that the app could be compromised via this vulnerability is considered high. Non-mobile variants are not affected. Mobile variants should update to the latest version provided by the platform appstore. There are no known workarounds for this vulnerability.

The Live Bookmarks page and the PDF viewer can run injected script content if a user pastes script from the clipboard into them while viewing RSS feeds or PDF files. This could allow a malicious site to socially engineer a user to copy and paste malicious script content that could then run with the context of either page but does not allow for privilege escalation. This vulnerability affects Firefox < 60.

Content Security Policy (CSP) is not applied correctly to all parts of multipart content sent with the "multipart/x-mixed-replace" MIME type. This could allow for script to run where CSP should block it, allowing for cross-site scripting (XSS) and other attacks. This vulnerability affects Firefox < 60.

URLs using "javascript:" have the protocol removed when pasted into the addressbar to protect users from cross-site scripting (XSS) attacks, but if a tab character is embedded in the "javascript:" URL the protocol is not removed and the script will execute. This could allow users to be socially engineered to run an XSS attack against themselves. This vulnerability affects Firefox < 59.

Long pressing on a download link could potentially provide a means for cross-site scripting This vulnerability affects Firefox for iOS < 129.

Insufficiently strict origin checks during JIT payment app installation in Payments in Google Chrome prior to 70.0.3538.67 allowed a remote attacker to install a service worker for a domain that can host attacker controled files via a crafted HTML page.

Documents loaded with the CSP sandbox directive could have escaped the sandbox's script restriction by embedding additional content. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.

The content security policy (CSP) "sandbox" directive did not create a unique origin for the document, causing it to behave as if the "allow-same-origin" keyword were always specified. This could allow a Cross-Site Scripting (XSS) attack to be launched from unsafe content. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.

Control characters prepended before "javascript:" URLs pasted in the addressbar can cause the leading characters to be ignored and the pasted JavaScript to be executed instead of being blocked. This could be used in social engineering and self-cross-site-scripting (self-XSS) attacks where users are convinced to copy and paste text into the addressbar. This vulnerability affects Firefox < 57.

A "data:" URL loaded in a new tab did not inherit the Content Security Policy (CSP) of the original page, allowing for bypasses of the policy including the execution of JavaScript. In prior versions when "data:" documents also inherited the context of the original page this would allow for potential cross-site scripting (XSS) attacks. This vulnerability affects Firefox < 57.

Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android, failed to require a user gesture for powerful download operations, which allowed a remote attacker who convinced a user to install a malicious extension to execute arbitrary code via a crafted HTML page.

Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android, had an insufficiently strict content security policy on the Chrome app launcher page, which allowed a remote attacker to inject scripts or HTML into a privileged page via a crafted HTML page.

If a page is loaded from an original site through a hyperlink and contains a redirect to a "data:text/html" URL, triggering a reload will run the reloaded "data:text/html" page with its origin set incorrectly. This allows for a cross-site scripting (XSS) attack. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.

Blink in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android, allowed attacker controlled JavaScript to be run during the invocation of a private script method, which allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page.

Blink in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android, incorrectly handled the sequence of events when closing a page, which allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page.

XSS Auditor in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android allowed detection of a blocked iframe load, which allowed a remote attacker to brute force JavaScript variables via a crafted HTML page.

When a "javascript:" URL is drag and dropped by a user into the addressbar, the URL will be processed and executed. This allows for users to be socially engineered to execute an XSS attack on themselves. This vulnerability affects Firefox < 53.

Blink in Google Chrome prior to 56.0.2924.76 for Linux, Windows and Mac, and 56.0.2924.87 for Android, incorrectly handled object owner relationships, which allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page.

Incorrect MIME type of XSS-Protection reports in Blink in Google Chrome prior to 58.0.3029.81 for Linux, Windows, and Mac, and 58.0.3029.83 for Android, allowed a remote attacker to circumvent Cross-Origin Resource Sharing checks via a crafted HTML page.

Lack of escaping allowed HTML injection when a webpage was viewed in Reader View. While a Content Security Policy prevents direct code execution, HTML injection is still possible. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 88.

Hubs Cloud allows users to download shared content, specifically HTML and JS, which could allow javascript execution in the Hub Cloud instance’s primary hosting domain.*. This vulnerability affects Hubs Cloud < mozillareality/reticulum/1.0.1/20210618012634.
