In Electron before versions 7.2.4, 8.2.4, and 9.0.0-beta21, there is a context isolation bypass. Code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions. Apps using contextIsolation are affected. This is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4.
In Electron before versions 7.2.4, 8.2.4, and 9.0.0-beta21, there is a context isolation bypass. Code running in the main world context in the renderer can reach into the isolated Electron context and perform privileged actions. Apps using contextIsolation are affected. This is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4.
### Impact Apps using `contextIsolation` 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` ### Non-Impacted Versions * `9.0.0-beta.*` ### For more information If you have any questions or comments about this advisory: * Email us at [security@electronjs.org](mailto:security@electronjs.org)

En Electron antes de las versiones 7.2.4, 8.2.4 y 9.0.0-beta21, se presenta una omisión de aislamiento de contexto. El código que se ejecuta en el contexto mundial principal en el renderizador puede alcanzar el contexto Electron aislado y llevar a cabo acciones privilegiadas. Las aplicaciones que usan contextIsolation están afectadas. Esto es corregido en las versiones 9.0.0-beta.21, 8.2.4 y 7.2.4
