CVE-2026-63738
SurrealDB 3.1.0 before 3.1.5 Field Permission Bypass via Traversal
Description

SurrealDB versions 3.1.0 before 3.1.5 fail to enforce field-level SELECT permissions when records are accessed through graph-edge or back-reference traversals. Attackers with table-level SELECT access can read field values hidden by field-level permissions by materializing records through graph traversals instead of direct table scans.
