Description
SurrealDB before 3.3.0 contains an authorization bypass vulnerability that allows record users to infer field values hidden by field-level SELECT permissions using LIVE SELECT WHERE predicates over $before or $after. Attackers can craft repeated predicates and observe whether notifications are delivered on CREATE, UPDATE, or DELETE to confirm or narrow restricted field values.
