No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
