SurrealDB before 2.2.2 Memory Exhaustion via Nested Functions
Impact
SurrealDB before 2.2.2 is vulnerable to memory exhaustion via nested functions. Authenticated attackers can trigger infinite recursion by chaining native and JavaScript function calls. This occurs when scripting is enabled and native functions contain embedded JavaScript that issues new queries.

Original source description
SurrealDB before 2.2.2 with scripting enabled fails to properly enforce recursion limits when native functions contain embedded JavaScript that issues new queries. Authenticated attackers can bypass the recursion limit by chaining native and JavaScript function calls to trigger infinite recursion and exhaust server memory.
