Summary
Electron: DevTools embedder handler executes arbitrary files via shell open
Details

Impact

The DevTools "reveal in file manager" action could launch the target file rather than reveal it. An attacker with a separate means of running script inside the DevTools frontend (such as a malicious DevTools extension) could use this to execute native code outside the sandbox.

Apps are only affected if DevTools is opened for windows exposed to untrusted content or untrusted DevTools extensions. Apps that do not open DevTools in that context are not affected.

Workarounds

Do not open DevTools for windows that load untrusted content, and do not load untrusted DevTools extensions.

Fixed Versions

  • 42.0.0-beta.3
  • 41.2.1
  • 40.9.2
  • 39.8.9
