### Description In OpenFGA, when iterator caching is enabled, two distinct check requests can produce the same cache key, leading to OpenFGA reusing an earlier cached result for a subsequent request. ### Preconditions This applies if the following preconditions are present: - FGA runs with SharedIteratorCache enabled, - FGA runs with ListObjectsIteratorCache enabled. ### Fix Upgrade to version 1.16.0 or greater. ### Acknowledgements OpenFGA would like to thank @j4xT for the discovery and the detailed report.
