## What is CVE-2026-115915?

CVE-2026-115915 is a high-severity vulnerability in Vllm Vllm, published on 26 Oct 2026. 

### Official description

vLLM is an inference and serving engine for large language models. Prior to 0.32.0, ImageMediaIO passes attacker-controlled image bytes to Pillow through Image.open(BytesIO(data)) without restricting decoder selection, and the MIME label does not constrain the selected format. Image-capable request paths through parse_image() and fetch_image() can therefore dispatch an EPS payload to host components. A host with Ghostscript affected by CVE-2024-29510 can execute commands with the vLLM process's privileges, while environments using Pillow 12.0.0 through 12.2.0 can trigger CVE-2026-59203 and exhaust media-loading workers. Deployments without the applicable vulnerable dependency are not affected by that corresponding impact. This issue is fixed in version 0.32.0.

Weakness: CWE-20 (Improper Input Validation), CWE-183 (Permissive List of Allowed Inputs)

Check this codebase for CVE-2026-115915 and fix it if it is affected.

What it is: CVE-2026-115915 is a high-severity vulnerability in Vllm Vllm, published on 26 Oct 2026. 
Exploitation: There is no known exploitation of CVE-2026-115915 in the wild and no public exploit code.

Affected packages and fixed versions:
- vllm (PyPI): affected all versions; fixed in 0.32.0
- vllm (PyPI): affected all versions; fixed in 0.32.0
- vllm (PyPI): affected from 0.30.0; fixed in 0.32.0

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
