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

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.
