Overview OpenFGA v1.3.8 to v1.8.2 (Helm chart openfga-0.1.38 to openfga-0.2.19, docker v1.3.8 to v.1.8.2) are vulnerable to authorization bypass when certain Check and ListObject calls are executed.

Am I Affected? You are affected by this authorization bypass vulnerability if you are using OpenFGA v1.3.8 to v1.8.2, specifically under the following conditions: 1. Calling Check API or ListObjects with a model that uses conditions, and 2. OpenFGA is configured with caching enabled (OPENFGACHECKQUERYCACHEENABLED), and 3. Check API call or ListObjects API calls contain contextual tuples that include conditions.

Fix Upgrade to v1.8.3. This upgrade is backwards compatible.

OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA v1.8.10 to v1.3.6 (Helm chart <= openfga-0.2.28, docker <= v.1.8.10) are vulnerable to authorization bypass when certain Check and ListObject calls are executed. This issue has been patched in version 1.8.11.

Overview OpenFGA v1.4.0 to v1.11.0 (openfga-0.1.34 <= Helm chart <= openfga-0.2.48, v.1.4.0 <= docker <= v.1.11.0) are vulnerable to improper policy enforcement when certain Check and ListObject calls are executed.

Am I Affected? You are affected by this vulnerability if you meet the following preconditions: - You are using OpenFGA v1.4.0 to v1.11.0 - The model has a a relation directly assignable by a type bound pubic access with condition - The same relation is not assignable by a type bound public access without condition - You have a type assigned for the same relation that is a type bound public access without condition

Fix Upgrade to v1.11.1. This upgrade is backwards compatible.

Workaround None

OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA < v1.8.4 (Helm chart < openfga-0.2.22, docker < v.1.8.4) are vulnerable to authorization bypass when certain Check and ListObject calls are executed. Users on OpenFGA v1.8.4 or previous, specifically under the following conditions are affected by this authorization bypass vulnerability: 1. Calling Check API or ListObjects with a model that has a relation directly assignable to both public access AND userset with the same type. 2. A type bound public access tuple is assigned to an object. 3. userset tuple is not assigned to the same object. and 4. Check request's user field is a userset that has the same type as the type bound public access tuple's user type. Users are advised to upgrade to v1.8.5 which is backwards compatible. There are no known workarounds for this vulnerability.
