OpenFGA Authorization Bypass via tupleset wildcard
Overview
During our internal security assessment, it was discovered that OpenFGA versions v0.2.3 and prior are vulnerable to authorization bypass under certain conditions.
Am I affected?
You are affected by this vulnerability if you are using openfga/openfga version v0.2.3 and you added a tuple with a wildcard (*) assigned to a tupleset relation (the right hand side of a ‘from’ statement).
How to fix that?
Upgrade to version v0.2.4.
Backward Compatibility
This update is not backward compatible with any authorization model that uses wildcard on a tupleset relation.

Связанные уязвимости
OpenFGA is an authorization/permission engine. Versions prior to version 0.2.4 are vulnerable to authorization bypass under certain conditions. Users who have wildcard (`*`) defined on tupleset relations in their authorization model are vulnerable. Version 0.2.4 contains a patch for this issue.
