## Threat activity

1 tracked threat campaign reference vllm-project products or exploit vllm-project CVEs:

- [BadHost CVE-2026-48710 — Starlette HTTP Host Header Authentication Bypass Affecting FastAPI/AI Infrastructure (MCP, vLLM, LiteLLM)](https://intel.threadlinqs.com/threat/TL-2026-0606) — CRITICAL — 2026-05-27

## How to prioritise vllm-project patching

This order follows the data Threadlinqs holds for vllm-project, not a generic severity checklist:

- No vllm-project CVE is in CISA KEV yet, so rank by exploit probability instead.
- Outside KEV, the highest EPSS scores are [CVE-2026-93436](https://intel.threadlinqs.com/cve/CVE-2026-93436) (0.5%), [CVE-2026-94622](https://intel.threadlinqs.com/cve/CVE-2026-94622) (0.4%), [CVE-2026-94623](https://intel.threadlinqs.com/cve/CVE-2026-94623) (0.4%).
- 0 CVEs score Critical and 6 High on CVSS v3 (maximum 7.5, average 6.6); sequence these after KEV and high-EPSS items.

## About this data
