Mozilla Firefox before Firefox 2.0.0.13, and SeaMonkey before 1.1.9, can automatically install TLS client certificates with minimal user interaction, and automatically sends these certificates when requested, which makes it easier for remote web sites to track user activities across domains by requesting the TLS client certificates from other domains.

Security readout for executives and security teams

Older Firefox and SeaMonkey could be used to plant and later request TLS client certificates with little user friction. This mainly creates a privacy and tracking risk: websites could identify the same user across domains more easily than expected. Exposure is likely limited to environments still using very old Firefox or SeaMonkey versions, or historical systems preserving their certificate stores. Modern managed browsers are unlikely to be affected by this specific legacy issue. Treat this as a legacy privacy exposure, not an emergency remote-code-execution event. Priority should be retiring unsupported browsers and checking old user profiles where sensitive browsing or regulated workflows occurred. Mitigation focus: Upgrade Firefox to 2.0.0.13 or later where legacy systems remain in use.; Upgrade SeaMonkey to 1.1.9 or later where legacy systems remain in use.; Remove untrusted or unexpected TLS client certificates from affected user profiles..
