# Use of hard-coded, security-relevant constants in deepset-ai/haystack

The farm-haystack Python package (deepset Haystack) ships security-relevant values hard-coded in the source, which the advisory classes as CWE-547. The sources do not say exactly what the constant controls, but the CVSS score of 9.8 means an unauthenticated remote attacker can likely compromise the affected service.

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

## Affected

- pypi:farm-haystack affected <= 1.15.0 fixed ?
- vendor:deepset haystack affected < 2023-03-29 fixed 2023-03-29

## How to check

- Run `pip show farm-haystack` and confirm the installed version is `1.15.0` or earlier.
- Check requirements files and lockfiles for `farm-haystack` pinned at `<=1.15.0`.

## Fix

- Upgrade `farm-haystack` to the release that includes commit `5fc84904f198de661d5b933fde756aa922bf09f1`; the fixed version number is unknown from the sources.

## Timeline
