## Overview

### Description
In OpenFGA, in specific scenarios, models using conditions with caching enabled can result in two different check requests producing the same cache key. This could result in OpenFGA reusing an earlier cached result for a subsequent request.

### Am I Affected?
Users are affected if their applications meet the following preconditions:

* The model has relations which rely on condition evaluation.
* Caching is enabled.

### Fix
Upgrade to OpenFGA v1.14.1.

### Acknowledgement
OpenFGA would like to thank @bugbunny-research for the detailed report.

## Affected packages

- `github.com/openfga/openfga < 1.14.1`

## Remediation

Upgrade to a patched release:

- `github.com/openfga/openfga 1.14.1`
