A critical security vulnerability exists in Starlette applications that use the Host header for authentication or routing, potentially exposing AI agents to remote control. Attackers can exploit this "BadHost" flaw to impersonate tenants, bypass access controls, and exfiltrate data by manipulating prompts and tool calls. Implementing robust security measures, such as using Nginx or Envoy proxies, validating Host headers, and employing guardrails, is crucial to protect AI agents from these sophisticated attacks. AI
