## Overview

vLLM before 0.31.0 contains a cache aliasing vulnerability that allows authenticated attackers to collide shared cache keys by supplying caller-controlled values such as EXIF ImageID or cache_salt. Attackers can set a UUID EXIF ImageID to receive another request's cached processed media, or match cache_salt to a LoRA name to reuse first-block KV state.

## Affected packages

- `vllm < 0.31.0`

## Remediation

Upgrade to a patched release:

- `vllm 0.31.0`
