CVE-2026-41523
vLLM: Security Check Bypass via assert Statement in Activation Function Loading Allows Arbitrary Code Execution
Overview
Description
vLLM is an inference and serving engine for large language models (LLMs). Prior to 0.22.0, an assert-based security check in vLLM's activation function loading allows any unauthenticated attacker to achieve arbitrary code execution on the server by publishing a malicious HuggingFace model, when vLLM runs in Python optimized mode (python -O or PYTHONOPTIMIZE=1). This vulnerability is fixed in 0.22.0.

Solution
Update vLLM to version 0.22.0 or later to fix arbitrary code execution vulnerability.
- Update vLLM to version 0.22.0 or later.
- Avoid running vLLM in Python optimized mode.
- Use only trusted HuggingFace models.

Action Type Old Value New Value Added Affected [{'vendor': 'vllm-project', 'product': 'vllm', 'versions': [{'status': 'affected', 'version': '< 0.22.0'}]}] Added Description vLLM is an inference and serving engine for large language models (LLMs). Prior to 0.22.0, an assert-based security check in vLLM's activation function loading allows any unauthenticated attacker to achieve arbitrary code execution on the server by publishing a malicious HuggingFace model, when vLLM runs in Python optimized mode (python -O or PYTHONOPTIMIZE=1). This vulnerability is fixed in 0.22.0. Added CVSS V3.1 AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H Added CWE CWE-94 Added CWE CWE-617 Added Reference https://github.com/vllm-project/vllm/commit/b3c7ffcab82c2439726f8cb213800f6f38c023d3 Added Reference https://github.com/vllm-project/vllm/security/advisories/GHSA-q8gq-377p-jq3r Added Reference https://huntr.com/bounties/dcb05b04-e625-41e7-adbc-bbae0cc2d64c
