Published by the GitHub Advisory Database at 28 Oct 2026, 21:15 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `vllm` (PyPI): affected `>=0.11.1, <0.32.0`; fixed in `0.32.0`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> vLLM versions from 0.11.1 before 0.32.0 that serve DeepSeek-OCR family models (DeepSeek-OCR, DeepSeek-OCR-2, or Unlimited-OCR) can be crashed by one unauthenticated chat request containing an image with a specific pixel distribution, under default configuration. The crash takes down the serving process, and the deployment stays down until it is manually restarted. Upgrade vLLM to 0.32.0 or later.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-gq5q-89c7-vhvx>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
