{"id":"CVE-2026-24851","summary":"OpenFGA Improper Policy Enforcement","details":"OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar. OpenFGA v1.8.5 to v1.11.2 ( openfga-0.2.22\u003c= Helm chart \u003c= openfga-0.2.51, v.1.8.5 \u003c= docker \u003c= v.1.11.2) are vulnerable to improper policy enforcement when certain Check calls are executed. The vulnerability requires a model that has a a relation directly assignable by a type bound public access and assignable by type bound non-public access, a tuple assigned for the relation that is a type bound public access, a tuple assigned for the same object with the same relation that is not type bound public access, and a tuple assigned for a different object that has an object ID lexicographically larger with the same user and relation which is not type bound public access. This vulnerability is fixed in v1.11.3.","aliases":["GHSA-jq9f-gm9w-rwm9","GO-2026-4446"],"modified":"2026-04-10T05:39:38.128214Z","published":"2026-02-06T17:51:27.274Z","related":["CGA-hmmj-94rh-r354","SUSE-SU-2026:0757-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24851.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/openfga/openfga/releases/tag/v1.11.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24851.json"},{"type":"ADVISORY","url":"https://github.com/openfga/openfga/security/advisories/GHSA-jq9f-gm9w-rwm9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24851"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openfga/helm-charts","events":[{"introduced":"6e62a289748908226f408895cbb1ba409949aeec"},{"fixed":"1cd1e7c8199be7f18a2920640f5c0a372a8b8a57"}],"database_specific":{"versions":[{"introduced":"0.2.22"},{"fixed":"0.2.51"}]}}],"versions":["openfga-0.2.22","openfga-0.2.23","openfga-0.2.24","openfga-0.2.25","openfga-0.2.26","openfga-0.2.27","openfga-0.2.28","openfga-0.2.29","openfga-0.2.30","openfga-0.2.31","openfga-0.2.32","openfga-0.2.33","openfga-0.2.34","openfga-0.2.35","openfga-0.2.36","openfga-0.2.37","openfga-0.2.38","openfga-0.2.39","openfga-0.2.40","openfga-0.2.41","openfga-0.2.42","openfga-0.2.43","openfga-0.2.44","openfga-0.2.45","openfga-0.2.46","openfga-0.2.47","openfga-0.2.48","openfga-0.2.49","openfga-0.2.50"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-24851.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/openfga/openfga","events":[{"introduced":"a77b33972c86b1c4ecb772bbcdcd4294af458469"},{"fixed":"6e22a3e972bdb5bce1095694857a709c192b4936"}]}],"versions":["v1.10.0","v1.10.1","v1.10.2","v1.10.3","v1.10.4","v1.10.5","v1.11.0","v1.11.1","v1.11.2","v1.8.10","v1.8.11","v1.8.12","v1.8.13","v1.8.14","v1.8.15","v1.8.5","v1.8.6","v1.8.7","v1.8.8","v1.8.9","v1.9.0","v1.9.2","v1.9.3","v1.9.4","v1.9.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-24851.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H"}]}
