Описание
OpenFGA has cache-key delimiter injection in shared-iterator and v2 iterator that caches enables intra-store authorization-decision poisoning
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.
