CVE-2025-55305
Electron has ASAR Integrity Bypass via resource modification
Impact
### Impact This only impacts apps that have the `embeddedAsarIntegrityValidation` and `onlyLoadAppFromAsar` [fuses](https://www.electronjs.org/docs/latest/tutorial/fuses) enabled. Apps without these fuses enabled are not impacted. Specifically this issue can only be exploited if your app is launched from a filesystem the attacker has write access too. i.e. the ability to edit files inside the `resources` folder in your app installation on Windows which these fuses are supposed to protect against. ### Workarounds There are no app side workarounds, you must update to a patched version of Electron. ### Fixed Versions * `38.0.0-beta.6` * `37.3.1` * `36.8.1` * `35.7.5` ### For more information If you have any questions or comments about this advisory, email us at [security@electronjs.org](mailto:security@electronjs.org)
