"The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 128.12. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2025-53 advisory.

  - The executable file warning did not warn users before opening files with the <code>terminal</code>
    extension.  This bug only affects Firefox for macOS. Other versions of Firefox are unaffected.
    (CVE-2025-6426)

  - A use-after-free in FontFaceSet resulted in a potentially exploitable crash. (CVE-2025-6424)

  - An attacker who enumerated resources from the WebCompat extension could have obtained a persistent UUID
    that identified the browser, and persisted between containers and normal/private browsing mode, but not
    profiles. (CVE-2025-6425)

  - Firefox could have incorrectly parsed a URL and rewritten it to the youtube.com domain when parsing the
    URL specified in an <code>embed</code> tag.  This could have bypassed website security checks that
    restricted which domains users were allowed to embed. (CVE-2025-6429)

  - When a file download is specified via the <code>Content-Disposition</code> header, that directive would be
    ignored if the file was included via a <code><embed></code> or <code><object></code> tag,
    potentially making a website vulnerable to a cross-site scripting attack. (CVE-2025-6430)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
