  6. CVE-2021-23968

    Medium · CVSS 4.3EPSS 1.31%Fix available

    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. 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.

  7. 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.

    Medium · CVSS 6.5EPSS 1.01%Fix available

    CVE-2021-23971

    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.

  9. CVE-2021-23972

    High · CVSS 8.8EPSS 1.01%Fix available

    CVE-2021-23972

    One phishing tactic on the web is to provide a link with HTTP Auth. For example 'https://[email protected]'. 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.
