    CVE-2021-23968

    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.

  2. CVE-2021-23969

    Medium · CVSS 4.3EPSS 1.21%Fix available

    CVE-2021-23969

    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.

    Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5.

    CVE-2020-26965

    Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password.

    CVE-2020-26961

    When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver.

This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
