Published: 2026-07-20 · updated 2026-07-22
Weakness: CWE-863

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.

Affected products

surrealdb: from 3.1.0 before 3.1.5 — fixed in 3.1.5

How to fix

Upgrade to a fixed version: surrealdb 3.1.5. Check the vendor advisory for mitigations.
