PYSEC-2026-4003

Quick fix

PYSEC-2026-4003 — vllm: upgrade to the fixed version with the command below.

pip install --upgrade 'vllm>=0.27.0'

Details

vLLM before 0.27.0 fails to properly classify DeepStream as a GPU backend and omits pixel-limit enforcement in its decode path. Unauthenticated attackers can activate DeepStream at request time to initialize the process-wide GPU decode pool and submit video that bypasses resource controls, causing partial denial of service for concurrent requests.
