Definition
An attack chain where a low-privilege user or internal service exploits vulnerabilities in an AI gateway to escalate to administrator privileges, then injects malicious callbacks into AI agent responses. The gateway becomes a pivot point for supply-chain style attacks.
Why it matters
AI gateways are central chokepoints that route requests to dozens of LLM providers and hold all provider API keys; compromise of the gateway exposes every configured provider credential and enables response injection attacks against all downstream agents.
