CVE-2026-63763Network attack vector

Privilege escalation via creator-unbounded field logic

Published Jul 20, 2026 · Updated Jul 20, 2026

Confused deputy flaws in SurrealDB before 2.5.0 and before 3.0.0-beta.3 allow remote authenticated users to gain elevated privileges. Stored futures, functions, and closures run with the querying or invoking user's authority instead of being limited to their creator's authority. An attacker who can create or modify such fields gains root-owner privileges and server control when a higher-privileged user reads, invokes, or writes the planted logic.
