VCID-1pcf-75nr-v3b7	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.	CVE-2021-23972
VCID-2h48-21h2-bbgs	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.	CVE-2021-23968
VCID-3y8m-vwcb-27b2	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.	CVE-2021-23976
VCID-55kj-h5g8-tqhj	Firefox for Android suffered from a time-of-check-time-of-use vulnerability that allowed a malicious application to read sensitive data from application directories.Note: This issue is only affected Firefox for Android. Other operating systems are unaffected.	CVE-2021-23977
VCID-61bf-8zpz-vyhz	Mozilla developers Alexis Beingessner, Tyson Smith, Nika Layzell, and Mats Palmgren reported memory safety bugs present in Thunderbird 78.7.

VCID-bxjd-dm71-4ua4	The developer page about:memory has a Measure function for exploring what object types the browser has allocated and their sizes.

VCID-cf28-37ns-xqdt	Mozilla developers Tyson Smith, Lars T Hansen, Valentin Gosu, and Sebastian Hengst reported memory safety bugs present in Firefox 85. 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.	CVE-2021-23979
VCID-esrg-38k2-5qbk	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.	CVE-2021-23971
VCID-kkes-taub-zucz	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, Thunderbird incorrectly set the source file to be the destination of the redirects. This was fixed to be the redirect destination's origin.	CVE-2021-23969
VCID-mrm7-fnxn-7fdq	When trying to load a cross-origin resource in an audio/video context a decoding error may have resulted, and the content of that error may have revealed information about the resource.	CVE-2021-23973
VCID-td48-8tdn-ubbt	The DOMParser API did not properly process <noscript> elements for escaping. This could be used as an mXSS vector to bypass an HTML Sanitizer.	CVE-2021-23974
