Mitigation checklist
- Restrict network access to the `/private/import_content/` endpoint of the `advisor-backend` service. Configure network policies or firewall rules to limit connections to this path to only trusted internal networks or localhost, preventing unauthenticated external access. This will reduce the attack surface by ensuring only authorized internal services can interact with the content import functionality. If the service is reloaded or restarted, ensure the network restrictions remain in effect.
