SCA: security update for vllm (GHSA-wcwg-c5fc-9vrc)

high Tenable Cloud Security Plugin ID 446105

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- vLLM versions 0.8.0 and later are vulnerable to an Out-of-Memory (OOM) Denial of Service (DoS) attack due
to unbounded frame count processing in the `VideoMediaIO.load_base64()` method. When processing
`video/jpeg` data URLs, the method splits the base64 data string on commas to extract individual JPEG
frames without enforcing a frame count limit. An attacker can exploit this by crafting a single API
request containing thousands of comma-separated base64-encoded JPEG frames in a data URL, causing the
server to decode all frames into memory and crash due to excessive memory consumption. This vulnerability
is reachable via the OpenAI-compatible chat completions API and does not require authentication.
(CVE-2026-5497)

Solution

Update the vllm library and its related packages to version 0.19.0 or later.
