Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-706: Use of Incorrectly-Resolved Name or Reference, where the product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. In Github.com/openfga/openfga, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
