Summary

OpenFGA's BatchCheck within-request deduplication produces incorrect authorization decisions via list-value cache-key collision

Description

OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. From 1.8.0 to 1.13.1, under specific conditions, BatchCheck calls with multiple checks sent for the same object, relation, and user combination can result in improper policy enforcement. This vulnerability is fixed in 1.14.0.
