Summary

Electron: Windows opened from a sandboxed top-level document do not inherit its sandbox restrictions

Details

Impact

Windows opened from a sandboxed top-level document did not inherit that document's HTML sandbox restrictions, so content that was meant to run sandboxed could open a window with the app's full origin. GHSA-hq2x-r82h-9wj4 covers the same issue for sandboxed iframes.

Apps are only affected if they render untrusted content in a sandboxed top-level document that allows popups. Apps that deny popups from untrusted content with setWindowOpenHandler are not affected.

Workarounds

Return { action: 'deny' } from setWindowOpenHandler for windows opened by untrusted content.

Fixed Versions

44.0.0-beta.5
43.4.1
42.9.2
41.10.6
