CVE-2020-36625Network attack vector

Cross-site WebSocket hijacking via permissive origin check

Published Dec 22, 2022 · Updated Aug 4, 2024

Cross-site request forgery in destiny.gg Chat allows remote attackers to issue unauthorized WebSocket actions through a victim's browser. The main.go WebSocket Upgrader overrides CheckOrigin with a callback that returns true for every request instead of comparing Origin and Host. Exploitation requires victim interaction and permits actions through the victim's session, with no CNA-reported data disclosure or service interruption.
