CVE-2026-114053

vLLM 0.7.3 before 0.31.0 RCE via mm_processor_kwargs.code_revision

Published Oct 21, 2026 CVSS 4.0 · 9.2 Critical EPSS < 1% KEV · Not listed
Description
vLLM from 0.7.3 before 0.31.0 forwards the request-supplied mm_processor_kwargs.code_revision to Transformers AutoProcessor.from_pretrained, letting clients select which revision of a model's dynamic processor code is imported when trust_remote_code is enabled. An attacker controlling a revision in the served model repository can send a multimodal request to the unauthenticated /tokenize endpoint to execute arbitrary Python in the vLLM API process.
