An LLM router or AI gateway that terminates TLS can view and rewrite tool call responses in plaintext before the client executes them, enabling response-side payload injection and arbitrary command execution. This bypasses model guardrails, prompt sanitization, and alignment because the attack happens after inference, and it can be amplified across chained routers such as OpenRouter or reseller-based API paths. #OpenRouter #Anthropic #OpenAI #Gemini #LlamaGuard #NeMoGuardrails
Keypoints
- An LLM router can read and modify plaintext responses between the model and the client.
- Tool call arguments can be rewritten after the model produces a safe response.
- Response-side payload injection can trigger arbitrary command execution on the client.
- Guardrails and prompt sanitization do not protect the response path.
- Chained routers and resellers increase exposure and make tampering harder to detect.
