Electron before versions 11.0.0-beta.6, 10.1.2, 9.3.1 or 8.5.2 is vulnerable to a context isolation bypass. Apps using both contextIsolation
and sandbox: true
are affected. Apps using both contextIsolation
and nodeIntegrationInSubFrames: 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.
