CVE-2020-4077 (GCVE-0-2020-4077)

Vulnerability from cvelistv5

Published

2020-07-07 00:05

Modified

2024-08-04 07:52

Severity ?

7.7 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N

CWE

CWE-501 - Trust Boundary Violation

Summary

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.
