Compromised child renderer processes could obtain IPC access without nodeIntegrationInSubFrames being enabled

  • Disclosed: 16.06.2022
  • Updated: 11.10.2026 10:22

Impact

This vulnerability allows a renderer with JS execution to obtain access to a new renderer process with nodeIntegrationInSubFrames enabled which in turn allows effective access to ipcRenderer.

Please note the misleadingly named nodeIntegrationInSubFrames option does not implicitly grant Node.js access rather it depends on the existing sandbox setting. If your application is sandboxed then nodeIntegrationInSubFrames just gives access to the sandboxed renderer APIs (which includes ipcRenderer).

If your application then additionally exposes IPC messages without IPC senderFrame validation that perform privileged actions or return confidential data this access to ipcRenderer can in turn compromise your application / user even with the sandbox enabled.

Patches

This has been patched and the following Electron versions contain the fix:

  • 18.0.0-beta.6
  • 17.2.0
  • 16.2.6
  • 15.5.5

Workarounds

Ensure that all IPC message handlers appropriately validate senderFrame as per our security tutorial here.
