Incorrect Authorization

CVE-2024-42473

High
9.8/10

Summary

OpenFGA is an authorization/permission engine. In github.com/openfga/openfga package versions v1.5.7 through 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 the time of publication, a patch is not available, but OpenFGA's maintainers are planning a patch for inclusion in a future release.

CWE-863 - Incorrect Authorization

Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
