The nsIScriptableUnescapeHTML.parseFragment method in the ParanoidFragmentSink protection mechanism in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 does not properly sanitize HTML in a chrome document, which makes it easier for remote attackers to execute arbitrary JavaScript with chrome privileges via a javascript: URI in input to an extension, as demonstrated by a javascript:alert sequence in (1) the HREF attribute of an A element or (2) the ACTION attribute of a FORM element.

Security readout for executives and security teams

This is an old Mozilla client vulnerability where unsafe HTML handling could let attacker-controlled content run script with browser chrome privileges through a vulnerable extension path. Impact could be serious on affected legacy Firefox, Thunderbird, or SeaMonkey installations, but the sources do not show current active exploitation. Exposure is mainly legacy systems running Firefox before 3.5.17 or 3.6.14, Thunderbird before 3.1.8, or SeaMonkey before 2.0.12, especially where extensions process remote or untrusted HTML input. Treat as urgent only if legacy Mozilla clients remain in use. For modern environments, this is mostly a historical exposure check and unsupported-software cleanup item. Mitigation focus: Upgrade affected Mozilla products to fixed versions or later.; Retire unsupported Firefox, Thunderbird, and SeaMonkey installations.; Review installed extensions that process untrusted HTML in chrome context..
