Electron: Incorrect origin passed to permission request handler for iframe requests
상세
### 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`
