Electron: Use-after-free in WebContents fullscreen, pointer-lock, and keyboard-lock permission callbacks
Quick fix
GHSA-8337-3p73-46f4 — electron: upgrade to the fixed version with the command below.
npm install electron@38.8.6Details
### Impact Apps that register an asynchronous `session.setPermissionRequestHandler()` may be vulnerable to a use-after-free when handling fullscreen, pointer-lock, or keyboard-lock permission requests. If the requesting frame navigates or the window closes while the permission handler is pending, invoking the stored callback dereferences freed memory, which may lead to a crash or memory corruption.
Apps that do not set a permission request handler, or whose handler responds synchronously, are not affected.
### Workarounds Respond to permission requests synchronously, or deny fullscreen, pointer-lock, and keyboard-lock requests if an asynchronous flow is required.
### Fixed Versions * `41.0.0-beta.8` * `40.7.0` * `39.8.0` * `38.8.6`
