## Beschreibung

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.
