"value": "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.\n\nApps using contextIsolation are affected.\n\nThis is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4."
