CVE-2020-4077 – Context isolation bypass via contextBridge in Electron

https://notcve.org/view.php?id=CVE-2020-4077

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 both `contextIsolation` and `contextBridge` are affected. This is fixed in versions 9.0.0-beta.21, 8.2.4 and 7.2.4. 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. • https://github.com/electron/electron/security/advisories/GHSA-h9jc-284h-533g https://www.electronjs.org/releases/stable?page=3#release-notes-for-v824 • CWE-501: Trust Boundary Violation •
