{"id":"CVE-2025-48371","aliases":["GHSA-c72g-53hw-82q7","GO-2025-3707"],"url":"https://o3.security/vulnerability/CVE-2025-48371","summary":"OpenFGA Authorization Bypass","details":"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.","published":"2025-05-22T22:20:37.570Z","modified":"2026-08-12T03:51:11.835734289Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/openfga/openfga","fixedVersion":"1.8.13"}],"fix":{"url":"https://github.com/openfga/openfga/commit/e5960d4eba92b723de8ff3a5346a07f50c1379ca","label":"openfga/openfga@e5960d4"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48371.json"},{"type":"ADVISORY","url":"https://github.com/openfga/openfga/security/advisories/GHSA-c72g-53hw-82q7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48371"},{"type":"FIX","url":"https://github.com/openfga/openfga/commit/e5960d4eba92b723de8ff3a5346a07f50c1379ca"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.835734289Z"}}
