Preliminary research

LLM Heist: auditing LiteLLM traffic rerouting, provider-key exposure and tool-call injection

Johann Rehberger · Embrace The Red · 3 August 2026

AI-collected research leads through 3 November 2026, including a November–October–September missed-article review and a targeted multilingual search alongside earlier community-source sweeps. Unranked, incomplete, not community-vetted, and subject to change.

Shows how an administrator credential can reroute a trusted LiteLLM gateway to an attacker proxy, causing provider credentials to be presented there. Subsequent forwarding and structured response modification enable traffic interception and tool-call injection, subject to the client’s tool permissions.
