Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.1, 40.8.1, and 41.0.0, when an iframe requests fullscreen, pointerLock, keyboardLock, openExternal, or media permissions, the origin passed to session.setPermissionRequestHandler() was the top-level page's origin rather than the requesting iframe's origin. Apps that grant permissions based on the origin parameter or webContents.getURL() may inadvertently grant permissions to embedded third-party content. The correct requesting URL remains available via details.requestingUrl. Apps that already check details.requestingUrl are not affected. This issue has been patched in versions 38.8.6, 39.8.1, 40.8.1, and 41.0.0.

 https://cve.radiocsirt.org/vuln/ghsa-r5p7-gp4j-qhrx GHSA-r5p7-gp4j-qhrx — Electron: Incorrect origin passed to permission request handler for iframe requests 2026-10-07T10:33:14.251319+00:00

Affected: npm: electron

### Impact When an iframe requests `fullscreen`, `pointerLock`, `keyboardLock`, `openExternal`, or `media` permissions, the origin passed to `session.setPermissionRequestHandler()` was the top-level page's origin rather than the requesting iframe's origin. Apps that grant permissions based on the origin parameter or `webContents.getURL()` may inadvertently grant permissions to embedded third-party content.

The correct requesting URL remains available via `details.requestingUrl`. Apps that already check `details.requestingUrl` are not affected.

### Workarounds In your `setPermissionRequestHandler`, inspect `details.requestingUrl` rather than the origin parameter or `webContents.getURL()` when deciding whether to grant `fullscreen`, `pointerLock`, `keyboardLock`, `openExternal`, or `media` permissions.

### Fixed Versions * `41.0.0` * `40.8.1` * `39.8.1` * `38.8.6`
