How to fix?
Upgrade surrealdb to version 1.1.0 or higher.
Overview
Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') via the WebSocket interface. An attacker can cause the server to consume high CPU by sending an HTTP request with excessively long headers during the client handshake, potentially leading to a denial of service.
Workaround
Users unable to update may limit access to the WebSocket interface via reverse proxy if not in use or only used by a limited number of trusted clients. Alternatively, a reverse proxy may be used to strip or truncate request headers exceeding a reasonable length before reaching the server.
