In short
OpenFGA versions 1.9.3 to 1.9.4 have a flaw where permission checks don't work correctly in certain situations, potentially allowing users to access resources they shouldn't be able to reach.
Technical detail
OpenFGA v1.9.3-1.9.4 fails to properly enforce authorization policies during specific Check and ListObject API calls due to improper access control logic (CWE-863). An attacker can bypass intended permission restrictions by exploiting these endpoints to gain unauthorized access to protected resources.
Summary generated and translated by AI from the official description.

This vulnerability is fixed in 1.9.5.
