Vulnerability from github – Published: 2026-08-28 21:31 – Updated: 2026-08-28 21:31

Details

Twenty through 2.35.0 contains an open redirect vulnerability in the OAuthPropagatorController.propagateOAuthCallback endpoint that treats the state query parameter as a redirect URL. Attackers can craft malicious requests to redirect users to arbitrary hosts while forwarding OAuth authorization codes, bypassing domain validation when IS_MULTIWORKSPACE_ENABLED is disabled.

Severity

4.7 (Medium)
