CVE-2026-63754 is a medium-severity flaw (CVSS 6.5) affecting surrealdb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
