Insufficient data authenticity validation In github.com/openfga/openfga
Description
OpenFGA has an Authorization Bypass through cached keys
Description
In OpenFGA, under specific conditions, models using conditions with caching enabled can result in two different check requests producing the same cache key. This can result in OpenFGA reusing an earlier cached result for a different request.
Am I Affected?
Users are affected if the following preconditions are met:
The model has relations which rely on condition evaluation.
Caching is enabled.
