SCA: security update for vllm (GHSA-mgrm-fgjv-mhv8)
medium Tenable Self-Hosted Container Security Plugin ID 421151
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. The outlines library
is one of the backends used by vLLM to support structured output (a.k.a. guided decoding). Outlines
provides an optional cache for its compiled grammars on the local filesystem. This cache has been on by
default in vLLM. Outlines is also available by default through the OpenAI compatible API server. The
affected code in vLLM is vllm/model_executor/guided_decoding/outlines_logits_processors.py, which
unconditionally uses the cache from outlines. A malicious user can send a stream of very short decoding
requests with unique schemas, resulting in an addition to the cache for each request. This can result in a
Denial of Service if the filesystem runs out of space. Note that even if vLLM was configured to use a
different backend by default, it is still possible to choose outlines on a per-request basis using the
guided_decoding_backend key of the extra_body field of the request. This issue applies only to the V0
engine and is fixed in 0.8.0. (CVE-2025-29770)
