CVE-2026-109342

SurrealDB from 3.0.0 before 3.3.0 contains a missing authentication vulnerability in the revoke RPC method that allows low-privileged or unauthenticated callers to invalidate other users' refresh tokens without proof of possession. Attackers can obtain grant identifiers via ACCESS SHOW ALL with VIEWER permission or leaked tokens, then permanently revoke refresh tokens to force re-authentication.
