CVE-2026-33729
Description
OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. In versions prior to 1.13.1, 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. Users are affected if the model has relations which rely on condition evaluation andncaching is enabled. OpenFGA v1.13.1 contains a patch.
