What is CVE-2026-22807?

The vLLM inference and serving engine for large language models has a vulnerability that allows arbitrary code execution. Versions from 0.10.1 up to, but not including, 0.14.0 are susceptible. The issue arises when vLLM loads dynamic modules from Hugging Face without proper validation of the trust_remote_code parameter, enabling an attacker to execute their own Python code during server startup simply by influencing the model repository. This exploit occurs before any API requests are processed, highlighting a significant security risk for deployments utilizing vLLM.
