Details

Arbitrary file read via window-open IPC in Electron ### Impact The vulnerability allows arbitrary local file read by defining unsafe window options on a child window opened via window.open. ### Workarounds Ensure you are calling `event.preventDefault()` on all [`new-window`](https://electronjs.org/docs/api/web-contents#event-new-window) events where the `url` or `options` is not something you expect. ### Fixed Versions * `9.0.0-beta.21` * `8.2.4` * `7.2.4` ### For more information If you have any questions or comments about this advisory: * Email us at [security@electronjs.org](mailto:security@electronjs.org)
