GHSA-G5WV-CVF4-2R98

Vulnerability from github – Published: 2024-11-26 15:31 – Updated: 2025-11-04 00:32
VLAI?
Details

The application failed to account for exceptions thrown by the loadManifestFromFile method during add-on signature verification. This flaw, triggered by an invalid or unsupported extension manifest, could have caused runtime errors that disrupted the signature validation process. As a result, the enforcement of signature validation for unrelated add-ons may have been bypassed. Signature validation in this context is used to ensure that third-party applications on the user's computer have not tampered with the user's extensions, limiting the impact of this issue. This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5.
