Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
SurrealDB versions 3.0.0 before 3.1.5 are vulnerable to denial of service. An authenticated user who can run queries can crash the server process with a single query containing a very long chain of operators, which denies service to all databases on that instance until it restarts. Upgrade to SurrealDB 3.1.5 or later. Workarounds include restricting arbitrary query execution with the --deny-arbitrary-query flag for untrusted user classes and running the server under a process manager that restarts it automatically.
