| CVE-2021-23972 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.8 High |
| 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. | ||||
| CVE-2021-23981 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.1 High |
| A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2021-23969 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-08-03 | 4.3 Medium |
| As specified in the W3C Content Security Policy draft, when creating a violation report, "User agents need to ensure that the source file is the URL requested by the page, pre-redirects. If that’s not possible, user agents need to strip the URL down to an origin to avoid unintentional leakage." Under certain types of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. | ||||
| CVE-2021-23982 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 6.5 Medium |
| Using techniques that built on the slipstream research, a malicious webpage could have scanned both an internal network's hosts as well as services running on the user's local machine utilizing WebRTC connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2021-23963 | 1 Mozilla | 1 Firefox | 2024-08-03 | 4.3 Medium |
| When sharing geolocation during an active WebRTC share, Firefox could have reset the webRTC sharing state in the user interface, leading to loss of control over the currently granted permission. This vulnerability affects Firefox < 85. | ||||
| CVE-2021-23985 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.5 Medium |
| If an attacker is able to alter specific about:config values (for example malware running on the user's computer), the Devtools remote debugging feature could have been enabled in a way that was unnoticable to the user. This would have allowed a remote attacker (able to make a direct network connection to the victim) to monitor the user's browsing activity and (plaintext) network traffic. This was addressed by providing a visual cue when Devtools has an open network socket. This vulnerability affects Firefox < 87. | ||||
| CVE-2021-23976 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.1 High |
| When accepting a malicious intent from other installed apps, Firefox for Android accepted manifests from arbitrary file paths and allowed declaring webapp manifests for other origins. This could be used to gain fullscreen access for UI spoofing and could also lead to cross-origin attacks on targeted websites. Note: This issue is a different issue from CVE-2020-26954 and only affected Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 86. | ||||
| CVE-2021-23986 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.5 Medium |
| A malicious extension with the 'search' permission could have installed a new search engine whose favicon referenced a cross-origin URL. The response to this cross-origin request could have been read by the extension, allowing a same-origin policy bypass by the extension, which should not have cross-origin permissions. This cross-origin request was made without cookies, so the sensitive information disclosed by the violation was limited to local-network resources or resources that perform IP-based authentication. This vulnerability affects Firefox < 87. | ||||
| CVE-2021-23960 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| Performing garbage collection on re-declared JavaScript variables resulted in a user-after-poison, and a potentially exploitable crash. This vulnerability affects Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7. | ||||
| CVE-2021-23962 | 1 Mozilla | 1 Firefox | 2024-08-03 | 8.8 High |
| Incorrect use of the '<RowCountChanged>' method could have led to a user-after-poison and a potentially exploitable crash. This vulnerability affects Firefox < 85. | ||||
| CVE-2021-23975 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.5 Medium |
| The developer page about:memory has a Measure function for exploring what object types the browser has allocated and their sizes. When this function was invoked we incorrectly called the sizeof function, instead of using the API method that checks for invalid pointers. This vulnerability affects Firefox < 86. | ||||
| CVE-2021-23954 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-03 | 8.8 High |
| Using the new logical assignment operators in a JavaScript switch statement could have caused a type confusion, leading to a memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7. | ||||
| CVE-2021-23974 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.1 Medium |
| The DOMParser API did not properly process '<noscript>' elements for escaping. This could be used as an mXSS vector to bypass an HTML Sanitizer. This vulnerability affects Firefox < 86. | ||||
| CVE-2021-23971 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.5 Medium |
| When processing a redirect with a conflicting Referrer-Policy, Firefox would have adopted the redirect's Referrer-Policy. This would have potentially resulted in more information than intended by the original origin being provided to the destination of the redirect. This vulnerability affects Firefox < 86. | ||||
| CVE-2021-23956 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.5 Medium |
| An ambiguous file picker design could have confused users who intended to select and upload a single file into uploading a whole directory. This was addressed by adding a new prompt. This vulnerability affects Firefox < 85. | ||||
| CVE-2021-23970 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.5 Medium |
| Context-specific code was included in a shared jump table; resulting in assertions being triggered in multithreaded wasm code. This vulnerability affects Firefox < 86. | ||||
| CVE-2021-23961 | 3 Debian, Mozilla, Redhat | 4 Debian Linux, Firefox, Enterprise Linux and 1 more | 2024-08-03 | 7.4 High |
| Further techniques that built on the slipstream research combined with a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. This vulnerability affects Firefox < 85. | ||||
| CVE-2021-23968 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-08-03 | 4.3 Medium |
| If Content Security Policy blocked frame navigation, the full destination of a redirect served in the frame was reported in the violation report; as opposed to the original frame URI. This could be used to leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. | ||||
| CVE-2021-23957 | 1 Mozilla | 1 Firefox | 2024-08-03 | 7.4 High |
| Navigations through the Android-specific `intent` URL scheme could have been misused to escape iframe sandbox. Note: This issue only affected Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 85. | ||||
| CVE-2021-23955 | 1 Mozilla | 1 Firefox | 2024-08-03 | 6.1 Medium |
| The browser could have been confused into transferring a pointer lock state into another tab, which could have lead to clickjacking attacks. This vulnerability affects Firefox < 85. | ||||
