Context isolation bypass via contextBridge in Electron
### Impact Apps using both `contextIsolation` and `contextBridge` 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 * `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)
