Name of the Vulnerable Software and Affected Versions OpenFGA versions prior to 0.2.5

Description OpenFGA is a high-performance authorization/permission engine inspired by Google Zanzibar. The issue allows for authorization bypass under certain conditions, specifically when a tuple with a wildcard (*) is assigned to a tupleset relation, which is the right-hand side of a 'from' statement. This affects authorization models that use wildcard on a tupleset relation.

Recommendations Upgrade to version 0.2.5, noting that this update is not backward compatible with any authorization model that uses wildcard on a tupleset relation. If using tuples where the user field is set to a userset and the tuple's relation is used on the right-hand side of a from statement, these tuples will need to be rewritten.
