CVE-2021-29960 1 Mozilla 1 Firefox 2021-09-20 4.3 MEDIUM 4.3 MEDIUM
Firefox used to cache the last filename used for printing a file. When generating a filename for printing, Firefox usually suggests the web page title. The caching and suggestion techniques combined may have lead to the title of a website visited during private browsing mode being stored on disk. This vulnerability affects Firefox < 89.
CVE-2021-29961 1 Mozilla 1 Firefox 2021-09-20 4.3 MEDIUM 4.3 MEDIUM

The attacker is restricted as they are unable to download non-quarantined files or supply command line arguments to the application, limiting the impact. Note: this issue only occurs on Mac OSX. Other operating systems are unaffected. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
CVE-2021-29983 2 Google, Mozilla 2 Android, Firefox 2021-08-25 4.3 MEDIUM 6.5 MEDIUM

This vulnerability affects Thunderbird < 78.12.
CVE-2021-29979 1 Mozilla 1 Hubs Cloud 2021-08-11 4.3 MEDIUM 6.1 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-2020-12407 1 Mozilla 1 Firefox 2021-07-21 2.6 LOW 6.5 MEDIUM
