HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.1. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

SurrealDB before 3.1.0 evaluates user-supplied WHERE clauses in SELECT statements (and SET/MERGE/CONTENT/PATCH clauses in UPDATE, UPSERT, INSERT ON DUPLICATE KEY UPDATE, and RELATE update-variant statements) against full record data before enforcing PERMISSIONS FOR SELECT WHERE restrictions. An authenticated user — including Record and Scope users — can exploit this ordering flaw to read the full contents of any table in the database they are authenticated against, bypassing table-level permission checks. Exfiltration is most direct when scripting functions are enabled (--allow-scripting), but is also possible via SurrealQL's THROW statement and timing-based side channels without scripting. The vulnerability is confined to the attacker's current database and does not cross namespace or database isolation boundaries.
