Microsoft introduced a new feature in Windows 10 known as Cloud Clipboard which, if enabled, will record data copied to the clipboard to the cloud, and make it available on other computers in certain scenarios. Applications that wish to prevent copied data from being recorded in Cloud History must use specific clipboard formats; and Firefox before versions 94 and ESR 91.3 did not implement them. This could have caused sensitive data to be recorded to a user's Microsoft account. *This bug only affects Firefox for Windows 10+ with Cloud Clipboard enabled. Other operating systems are unaffected.*. • https://bugzilla.mozilla.org/show_bug.cgi?id=1730194 https://www.mozilla.org/security/advisories/mfsa2021-48 https://www.mozilla.org/security/advisories/mfsa2021-49 https://www.mozilla.org/security/advisories/mfsa2021-50 • CWE-668: Exposure of Resource to Wrong Sphere •

When a user loaded a Web Extensions context menu, the Web Extension could access the post-redirect URL of the element clicked. If the Web Extension lacked the WebRequest permission for the hosts involved in the redirect, this would be a same-origin-violation leaking data the Web Extension should have access to. This was fixed to provide the pre-redirect URL. This is related to CVE-2021-43532 but in the context of Web Extensions. This vulnerability affects Firefox < 94. • https://bugzilla.mozilla.org/show_bug.cgi?id=1659155 https://www.mozilla.org/security/advisories/mfsa2021-48 • CWE-346: Origin Validation Error •

The 'Copy Image Link' context menu action would copy the final image URL after redirects. By embedding an image that triggered authentication flows - in conjunction with a Content Security Policy that stopped a redirection chain in the middle - the final image URL could be one that contained an authentication token used to takeover a user account. If a website tricked a user into copy and pasting the image link back to the page, the page would be able to steal the authentication tokens. This was fixed by making the action return the original URL, before any redirects. This vulnerability affects Firefox < 94. • https://bugzilla.mozilla.org/show_bug.cgi?id=1719203 https://www.mozilla.org/security/advisories/mfsa2021-48 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
