### [CVE-2024-11696](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-11696) ![](https://img.shields.io/static/v1?label=Product&message=Firefox%20ESR&color=blue) ![](https://img.shields.io/static/v1?label=Product&message=Firefox&color=blue) ![](https://img.shields.io/static/v1?label=Product&message=Thunderbird&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=0%20&color=brightgreen) ![](https://img.shields.io/static/v1?label=Version&message=unspecified%20&color=brightgreen) ![](https://img.shields.io/static/v1?label=Vulnerability&message=Unhandled%20Exception%20in%20Add-on%20Signature%20Verification&color=brightgreen) ### Description 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. ### POC #### Reference No PoCs from references. #### Github - https://github.com/ARPSyndicate/cve-scores
