Mitigation checklist
- To mitigate the risk of unauthenticated access, restrict network access to the LiteLLM proxy's management routes. Configure network firewalls or security groups to permit inbound connections only from trusted internal networks. This operational control limits the exposure of vulnerable endpoints to unauthorized external access. If the LiteLLM proxy is deployed behind a load balancer or API gateway, ensure these components are configured to strictly validate and sanitize the HTTP Host header before forwarding requests.
