The Web Workers implementation in Mozilla Firefox before 23.0, Firefox ESR 17.x before 17.0.8, Thunderbird before 17.0.8, Thunderbird ESR 17.x before 17.0.8, and SeaMonkey before 2.20 does not properly restrict XMLHttpRequest calls, which allows remote attackers to bypass the Same Origin Policy and conduct cross-site scripting (XSS) attacks via unspecified vectors.

Security readout for executives and security teams

This is an old Mozilla client vulnerability where web pages could abuse Web Workers to bypass browser same-origin protections and run cross-site scripting attacks. The main business risk is legacy exposure: unmanaged or embedded systems still using affected Firefox, Thunderbird, or SeaMonkey versions. Exposure is most likely on legacy desktops, kiosks, lab systems, or old Debian-derived images that still include affected Mozilla packages. Modern fully patched browsers should not be affected based on the fixed-version boundaries in the sources. Treat this as a legacy hygiene issue unless affected clients are still present. If obsolete Mozilla clients remain in production, remediate promptly because browser same-origin bypasses can expose user sessions and sensitive web data. Mitigation focus: Upgrade Firefox to 23.0 or later where applicable.; Upgrade Firefox ESR or Thunderbird ESR to 17.0.8 or later.; Upgrade SeaMonkey to 2.20 or later where applicable..
