# Shimmy: inference API lacks authentication, allowing remote access

Link for people: https://infrastack.ai/live/CVE-2026-125087 (this .md is for agents)

Shimmy, a Rust server that runs local language models, has an inference API in src/server.rs that does not require authentication. A remote attacker can send requests to it without credentials.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:shimmy affected range not listed fixed no fixed version listed

## How to check

- Check the installed Shimmy version; versions up to `2.6.4` are affected.
- Check whether the Inference API is reachable from networks other than the local machine.

## Fix

- Shimmy: upgrade to `2.6.5`.
