| CVE-2023-45810 | 1 Openfga | 1 Openfga | 2024-11-21 | 5.3 Medium |
| OpenFGA is a flexible authorization/permission engine built for developers and inspired by Google Zanzibar. Affected versions of OpenFGA are vulnerable to a denial of service attack. When a number of `ListObjects` calls are executed, in some scenarios, those calls are not releasing resources even after a response has been sent, and given a sufficient call volume the service as a whole becomes unresponsive. This issue has been addressed in version 1.3.4 and the upgrade is considered backwards compatible. There are no known workarounds for this vulnerability. | ||||
| CVE-2023-43645 | 1 Openfga | 1 Openfga | 2024-11-21 | 5.9 Medium |
| OpenFGA is an authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA is vulnerable to a denial of service attack when certain Check calls are executed against authorization models that contain circular relationship definitions. When the call is made, it's possible for the server to exhaust resources and die. Users are advised to upgrade to v1.3.2 and update any offending models. There are no known workarounds for this vulnerability. Note that for models which contained cycles or a relation definition that has the relation itself in its evaluation path, checks and queries that require evaluation will no longer be evaluated on v1.3.2+ and will return errors instead. Users who do not have cyclic models are unaffected. | ||||
| CVE-2023-40579 | 1 Openfga | 1 Openfga | 2024-11-21 | 6.5 Medium |
| OpenFGA is an authorization/permission engine built for developers and inspired by Google Zanzibar. Some end users of OpenFGA v1.3.0 or earlier are vulnerable to authorization bypass when calling the ListObjects API. The vulnerability affects customers using `ListObjects` with specific models. The affected models contain expressions of type `rel1 from type1`. This issue has been patched in version 1.3.1. | ||||
| CVE-2024-42473 | 1 Openfga | 1 Openfga | 2024-10-01 | 7.5 High |
| OpenFGA is an authorization/permission engine. OpenFGA v1.5.7 and v1.5.8 are vulnerable to authorization bypass when calling Check API with a model that uses `but not` and `from` expressions and a userset. Users should downgrade to v1.5.6 as soon as possible. This downgrade is backward compatible. As of time of publication, a patch is not available but OpenFGA's maintainers are planning a patch for inclusion in a future release. | ||||
