Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, serial-port and media permission checks made from an iframe passed the top-level frame origin to session.setPermissionCheckHandler instead of the requesting iframe origin. Origin-based handler logic could grant a cross-origin iframe device access intended only for the top-level origin. This issue is fixed in 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1.

GHSA-9pf5-hg6p-4pwpElectron: Permission Check Handler Receives Main Frame Origin Instead of Requesting Iframe Origin2026-08-05ghsa · osvUS
### Impact For serial-port and media (camera / microphone) permission checks made from an iframe, the `requestingOrigin` passed to `session.setPermissionCheckHandler` was the top-level frame's origin rather than the requesting frame's. Origin-based handler logic could therefore grant a cross-origin iframe device access intended only for the top-level origin. Apps are only affected if they use `setPermissionCheckHandler` with origin-based logic and embed cross-origin iframes with delegated device permissions. Apps that base the decision on `details.securityOrigin`, or that do not embed such iframes, are not affected. ### Workarounds Check `details.securityOrigin` instead of `requestingOrigin` for these permissions, or do not delegate device permissions to untrusted iframes. ### Fixed Versions * `42.0.0-beta.1` * `41.2.0` * `40.9.0` * `39.8.7` ### For more information If you have any questions or comments about this advisory, email Electron at [security@electronjs.org](mailto:security@electronjs.org)
