Your AI gateway just became the backdoor. CISA says patch by yesterday.

LiteLLM — the open-source LLM gateway buried inside CrewAI, DSPy, Microsoft GraphRAG, and AutoGen — is under active exploitation.

CVE-2026-42271. Command injection. Chain it with a Starlette auth bypass and you get unauthenticated CVSS 10.0 remote code execution.

Any authenticated user. Low-privilege keys. Arbitrary commands on the host.

That host holds your model API keys. Your cloud credentials. Your tenant routing. Everything an attacker needs to own your AI tier.

CISA added it to the KEV catalog on June 8.

Remediation deadline: June 22.

That was four days ago.

If you haven't patched, you are now in non-compliance with BOD 22-01. Federal agencies face mandatory remediation. Your private-sector exposure is just as real — your regulators will ask.

This is the second critical incident in LiteLLM in four months. In March, the PyPI package was backdoored for three hours. 47,000 downloads. An autonomous attack bot named hackerbot-claw rode alongside every install.

Your agentic AI stack has a single point of failure, and it keeps breaking.

Audit your LLM gateway today. Check your LiteLLM version. If it's below 1.83.7, stop everything and patch. Rotate every credential that gateway ever touched.

The AI layer is no longer the innovation layer. It's the attack surface.
