CVE-2023-35933 1 Openfga 1 Openfga 2024-12-03 5.9 Medium
OPenFGA is an open source authorization/permission engine built for developers. OpenFGA versions v1.1.0 and prior are vulnerable to a DoS attack when Check and ListObjects calls are executed against authorization models that contain circular relationship definitions. Users are affected by this vulnerability if they are using OpenFGA v1.1.0 or earlier, and if you are executing `Check` or `ListObjects` calls against a vulnerable authorization model. Users are advised to upgrade to version 1.1.1. There are no known workarounds for this vulnerability. Users that do not have circular relationships in their models are not affected.
CVE-2024-31452 1 Openfga 1 Openfga 2024-11-21 8.1 High
OpenFGA is a high-performance and flexible authorization/permission engine. Some end users of OpenFGA v1.5.0 or later are vulnerable to authorization bypass when calling Check or ListObjects APIs. You are very likely affected if your model involves exclusion (e.g. `a but not b`) or intersection (e.g. `a and b`). This vulnerability is fixed in v1.5.3.
CVE-2024-23820 1 Openfga 1 Openfga 2024-11-21 5.3 Medium
OpenFGA, an authorization/permission engine, is vulnerable to a denial of service attack in versions prior to 1.4.3. In some scenarios that depend on the model and tuples used, a call to `ListObjects` may not release memory properly. So when a sufficiently high number of those calls are executed, the OpenFGA server can create an `out of memory` error and terminate. Version 1.4.3 contains a patch for this issue.
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-2022-39352 1 Openfga 1 Openfga 2024-11-21 4.8 Medium
OpenFGA is a high-performance authorization/permission engine inspired by Google Zanzibar. Versions prior to 0.2.5 are vulnerable to authorization bypass under certain conditions. You are affected by this vulnerability if you added a tuple with a wildcard (*) assigned to a tupleset relation (the right hand side of a ‘from’ statement). This issue has been patched in version v0.2.5. This update is not backward compatible with any authorization model that uses wildcard on a tupleset relation.
CVE-2022-39342 1 Openfga 1 Openfga 2024-11-21 5.9 Medium
OpenFGA is an authorization/permission engine. Versions prior to version 0.2.4 are vulnerable to authorization bypass under certain conditions. Users whose model has a relation defined as a tupleset (the right hand side of a ‘from’ statement) that involves anything other than a direct relationship (e.g. ‘as self’) are vulnerable. Version 0.2.4 contains a patch for this issue.
CVE-2022-39341 1 Openfga 1 Openfga 2024-11-21 5.9 Medium
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.
CVE-2022-39340 1 Openfga 1 Openfga 2024-11-21 5.3 Medium
OpenFGA is an authorization/permission engine. Prior to version 0.2.4, the `streamed-list-objects` endpoint was not validating the authorization header, resulting in disclosure of objects in the store. Users `openfga/openfga` versions 0.2.3 and prior who are exposing the OpenFGA service to the internet are vulnerable. Version 0.2.4 contains a patch for this issue.
CVE-2022-23542 1 Openfga 1 Openfga 2024-11-21 7.7 High
OpenFGA is an authorization/permission engine built for developers and inspired by Google Zanzibar. During an internal security assessment, it was discovered that OpenFGA version 0.3.0 is vulnerable to authorization bypass under certain conditions. This issue has been patched in version 0.3.1 and is backward compatible.
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.
