No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
