CyberRota Analysis

AI-Generated

SurrealDB versions prior to 3.1.0 are susceptible to a denial of service vulnerability that allows authenticated users with select permissions to disrupt all write operations (CREATE, UPDATE, DELETE) on a monitored table by executing malicious LIVE queries that generate evaluation errors. This can effectively lock out all users, including administrators, from performing write operations until the offending query is terminated or the session is closed. Organizations using SurrealDB should prioritize updating to version 3.1.0 or later to mitigate this risk.

Original NVD 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.
