Summary

SurrealDB before 3.3.0 contains an authorization bypass. A record user with low privileges can infer field values hidden by field-level SELECT permissions by using LIVE SELECT WHERE predicates over $before or $after. The attacker repeats predicates and observes whether notifications are delivered on CREATE, UPDATE, or DELETE to confirm or narrow restricted values. This is classified as CWE-203 (Observable Discrepancy).
