Prior to 1.142.6, 1.143.3, 1.144.2, and 1.145.0, the customverbauthorizer admission plugin's mustCheckProjectMembers manage-members check compares changes to User subjects but does not account for Group or ServiceAccount subjects in Project.spec.members. A project administrator who lacks manage-members permission can add arbitrary Group or ServiceAccount subjects, including the system:authenticated Group, and thereby grant broad project access. The resulting access can include Shoots, Secrets, and cloud provider credentials. This issue is fixed in versions 1.142.6, 1.143.3, 1.144.2, and 1.145.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:H/A:N","score":5.5},"cwes":["CWE-863"],"references":["https://github.com/gardener/gardener/commit/63751db97dca6cc5ee5f966d4963415de6ae5545","https://github.com/gardener/gardener/pull/15080","https://github.com/gardener/gardener/releases/tag/v1.144.2","https://github.com/gardener/gardener/security/advisories/GHSA-gfjv-gqf2-c888"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-79767","score":0.00389,"percentile":0.33036,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gfjv-gqf2-c888","url":"https://osv.dev/vulnerability/GHSA-gfjv-gqf2-c888","summary":"Gardener: Authorization Bypass via Group Subject Injection","modified":"2026-10-01T20:55:38.499786900Z","packages":[{"ecosystem":"Go","name":"github.com/gardener/gardener","purl":"pkg:golang/github.com/gardener/gardener","ranges":["<1.142.6"],"fixed":["1.142.6"]},{"ecosystem":"Go","name":"gardener/gardener","purl":"pkg:golang/gardener/gardener","ranges":[">=1.143.0 <1.143.3"],"fixed":["1.143.3"]},{"ecosystem":"Go","name":"gardener/gardener","purl":"pkg:golang/gardener/gardener","ranges":[">=1.144.0 <1.144.2"],"fixed":["1.144.2"]}]},{"id":"GO-2026-6568","url":"https://osv.dev/vulnerability/GO-2026-6568","summary":"Gardener: Authorization Bypass via Group Subject Injection in gardener/gardener","modified":"2026-10-01T20:45:13.175814132Z","packages":[{"ecosystem":"Go","name":"github.com/gardener/gardener","purl":"pkg:golang/github.com/gardener/gardener","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/gardener/gardener","purl":"pkg:golang/github.com/gardener/gardener","ranges":["<1.142.6"],"fixed":["1.142.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
