vulnerability as referenced in the mfsa2025-19 advisory.

  - Following the recent Chrome sandbox escape (CVE-2025-2783), various Firefox developers identified a
    similar pattern in our IPC code. A compromised child process could cause the parent process to return an
    unintentionally powerful handle, leading to a sandbox escape.  The original vulnerability was being
    exploited in the wild.  This only affects Firefox on Windows. Other operating systems are unaffected.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
