OpenFGA Authorization Bypass

State: Published
Severity: 7.5 High
Published: Aug 9, 2024
Updated: Aug 10, 2024
Reserved: Aug 2, 2024

Description

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.
