AI SECURITY PULSE
Hello!
Welcome to issue #2 of Secure Prompt’s Threat Wire.
Trust boundaries collapsed across the AI stack this week. Starlette — the foundational ASGI engine underneath vLLM, LiteLLM, Ray Serve, and most MCP gateways — disclosed a critical authentication bypass. Six AI coding agents fell to the same symlink-based architectural attack. Sysdig captured the first confirmed real-world LLM-agent-driven intrusion in production. Hugging Face hit its trending chart with 244,000 downloads of a fake OpenAI privacy filter that turned out to be an infostealer. Five stories. One pattern: AI infrastructure isn't being attacked at the model layer anymore. It's being attacked at every layer beneath it.
