Context isolation bypass in Electron
### Impact Apps using both `contextIsolation` and `sandbox: true` are affected. Apps using both `contextIsolation` and `nativeWindowOpen: true` are affected. This is a context isolation bypass, meaning that code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions. ### Workarounds There are no app-side workarounds, you must update your Electron version to be protected. ### Fixed Versions * `11.0.0-beta.6` * `10.1.2` * `9.3.1` * `8.5.2` ### For more information If you have any questions or comments about this advisory: * Email us at [security@electronjs.org](mailto:security@electronjs.org)
