CVE-2026-115914 · Severity: medium · CVSS 6.5 · Published 2026-10-26

vLLM is an inference engine for large language models that supports vision capabilities. An attacker with network access to the OpenAI-compatible API can submit a specially crafted image whose pixel values sum to zero, causing the engine to crash and deny service to all other users. This requires only the ability to reach the API endpoint and send a valid image file.

Technologies: vllm (PyPI), Vllm. Vendors: PyPI, Vllm.

```
pip install "vllm>=0.32.0"
```

Technical details

The vulnerability exists in the DeepSeek-OCR, DeepSeek-OCR-2, and Unlimited-OCR image path processing. When an image's normalized pixel tensor sums to exactly zero, _parse_and_validate_image_input returns None instead of an embedding, which propagates through embed_multimodal and triggers a fatal assertion in sanity_check_mm_encoder_outputs, crashing the entire inference engine. The attack requires network access to the API but no authentication or user interaction.

Affected products
