Summary
ASAR Integrity bypass via filetype confusion in electron
Details

Impact

This only impacts apps that have the embeddedAsarIntegrityValidation and onlyLoadAppFromAsar fuses enabled. Apps without these fuses enabled are not impacted. This issue is specific to macOS as these fuses are only currently supported on macOS.

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

  • 27.0.0-alpha.7
  • 26.2.1
  • 25.8.1
  • 24.8.3
  • 22.3.24
