SurrealDB before 3.1.0 Denial of Service via LIVE Query

Published Jul 20, 2026 · Updated Jul 28, 2026 · Assigned by VulnCheck

Description

SurrealDB versions before 3.1.0 contain a denial of service vulnerability where malicious LIVE queries with WHERE clauses that evaluate to errors cause all CREATE, UPDATE, and DELETE operations on the watched table to fail. An authenticated user with only select permission can prevent write operations on a table for any user, including root, by registering a LIVE query that triggers evaluation errors until the query is killed or the session ends.
