CVE-2026-63755 | BDVDB-2026-350107 Detail

Description#

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.
