Summary

OpenFGA Authorization Bypass

Details

Overview

OpenFGA v1.8.0 to v1.8.12 ( openfga-0.2.16 <= Helm chart <= openfga-0.2.31, v1.8.0 <= docker <= v.1.8.12) are vulnerable to authorization bypass when certain Check and ListObject calls are executed.

Am I Affected?

If you are using OpenFGA v1.8.0 to v1.8.12, specifically under the following conditions, you are affected by this authorization bypass vulnerability: - Calling Check API or ListObjects with an authorization model that has a relationship directly assignable by both type bound public access and userset, and - There are check or list object queries with contextual tuples for the relationship that can be directly assignable by both type bound public access and userset, and - Those contextual tuples’s user field is an userset, and - Type bound public access tuples are not assigned to the relationship

Fix

Upgrade to v1.8.13. This upgrade is backwards compatible.

Acknowledgments

OpenFGA would like to thank @udyvish for discovering this vulnerability.

CVE-2025-48371 (GCVE-0-2025-48371)

Vulnerability from cvelistv5 – Published: 2025-05-22 22:20 – Updated: 2025-05-23 14:14

Title

OpenFGA Authorization Bypass

Summary

OpenFGA is an authorization/permission engine. OpenFGA versions 1.8.0 through 1.8.12 (corresponding to Helm chart openfga-0.2.16 through openfga-0.2.30 and docker 1.8.0 through 1.8.12) are vulnerable to authorization bypass when certain Check and ListObject calls are executed. Users are affected under four specific conditions: First, calling Check API or ListObjects with an authorization model that has a relationship directly assignable by both type bound public access and userset; second, there are check or list object queries with contextual tuples for the relationship that can be directly assignable by both type bound public access and userset; third, those contextual tuples’s user field is an userset; and finally, type bound public access tuples are not assigned to the relationship. Users should upgrade to version 1.8.13 to receive a patch. The upgrade is backwards compatible.
