CVE-2026-63748

Description

SurrealDB versions before 3.1.0 contain an information disclosure vulnerability where authenticated users with UPDATE access can read field values hidden by field-level SELECT permissions through error messages. Attackers can trigger arithmetic or extend operations on hidden fields to embed raw operand values in error responses, bypassing field-level access controls.
