SurrealDB versions before 3.1.0 contain a session hijacking vulnerability where the HTTP /rpc sessions method returns attached session UUIDs without authentication and accepts arbitrary session fields with no ownership verification. Unauthenticated attackers can enumerate session UUIDs and impersonate authenticated sessions to read, write, delete data and escalate privileges.
