SurrealDB before 3.2.0 Authentication Bypass via Custom API

SurrealDB versions before 3.2.0 fail to validate namespace and database scope in custom API routes, allowing authenticated users to invoke endpoints in different namespaces/databases. Attackers with valid credentials for any namespace/database can access custom API endpoints in other tenants by specifying the target scope in the URL path, reading sensitive data or triggering unintended operations.
