The Content Security Policy (CSP) implementation in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 does not block inline event handlers, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted HTML document.

Security readout for executives and security teams

This flaw weakens a browser or mail client defense that was supposed to limit malicious script behavior. In affected Mozilla products, CSP did not block inline event handlers, making cross-site scripting attacks easier when a user viewed crafted HTML. The practical concern is mainly legacy systems still running 2012-era Mozilla software. Current exposure is most likely limited to legacy desktops, old Linux distributions, embedded workstations, or archived virtual machines using the listed Mozilla versions. Modern supported Mozilla releases are not identified as affected in the provided sources. Treat this as a legacy exposure cleanup item. It is not KEV-listed in the provided data, but any remaining affected client software indicates unsupported technology that can weaken browser-side protections against malicious HTML. Mitigation focus: Identify any Firefox, Thunderbird, Thunderbird ESR, Firefox ESR, or SeaMonkey versions in the affected ranges.; Upgrade affected Mozilla products beyond the vulnerable versions named in the advisories.; Use OS vendor security updates where Mozilla packages are distribution-managed..
