Summary

SurrealDB from 3.0.0 before 3.3.0 has missing authentication (CWE-306) in its revoke RPC method. Low-privileged or unauthenticated callers can invalidate other users' refresh tokens without proving possession of them. Attackers can obtain grant identifiers through ACCESS SHOW ALL with VIEWER permission or from leaked tokens, then permanently revoke refresh tokens to force re-authentication.
