The mozIJSSubScriptLoader.LoadScript function in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 does not apply XPCNativeWrappers to scripts loaded from (1) file: URIs, (2) data: URIs, or (3) certain non-canonical chrome: URIs, which allows remote attackers to execute arbitrary code via vectors involving third-party add-ons.

Security readout for executives and security teams

This is a legacy Mozilla flaw where certain add-on-loaded scripts could bypass a safety wrapper. In affected Firefox, Thunderbird, and SeaMonkey versions, a remote attacker could potentially execute arbitrary code, but the CVE ties this to third-party add-on vectors. Exposure is most likely in legacy endpoints still running the named Mozilla versions, especially where third-party add-ons are installed or allowed. The source bundle does not identify affected modern Mozilla releases or non-Mozilla products. Treat this as high priority only where legacy Mozilla software remains in use. For normal modern fleets, priority is usually inventory confirmation and cleanup rather than emergency response. Mitigation focus: Upgrade or remove affected Firefox, Thunderbird, and SeaMonkey versions.; Use vendor or Linux distribution advisories for exact package versions.; Disable or remove unneeded third-party add-ons on legacy systems..
