Summary

SurrealDB has unauthenticated remote DoS via malformed RPC `use` call

Details

A single unauthenticated WebSocket message to /rpc crashed the SurrealDB server. Sending use { db: "x" } without first selecting a namespace hit .expect("namespace should be set") in the use handler; because surrealdb-core is built with panic = 'abort', the panic terminated the process. use is callable before signin, and the per-method capability check passes by default for guest callers — so no credentials, token, or --allow-guests flag are required.

Impact

An unauthenticated remote attacker who could reach the /rpc endpoint could crash the SurrealDB server with a single WebSocket message. No credentials, token, session knowledge, or capability are required.

Patches

A patch has been introduced that returns a typed invalid_params response when db is set on a session with no ns, replacing the panic.

Versions 3.1.0 and later are not affected by this issue.

Workarounds

Affected users who are unable to update should restrict network access to the /rpc endpoint to trusted clients, and run SurrealDB under a process supervisor that restarts on crash.
