SurrealDB from 3.0.0 before 3.3.0 contains an information disclosure vulnerability that allows record users to read values hidden by field-level SELECT permissions through COMPUTED fields. Attackers can select records whose readable COMPUTED fields derive from hidden fields, or use write RETURN clauses with $before/$after to expose hidden values.
