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.","state":0,"publishedAt":"2026-09-22T19:58:00.09+00:00","modifiedAt":"2026-09-23T14:36:18.501+00:00","affected":[{"ecosystem":"Vendor product","name":"gardener","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"gardener\",\n                    \"product\": \"gardener\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.142.6\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.143.0, < 1.143.3\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 1.144.0, < 1.144.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/gardener/gardener/security/advisories/GHSA-gfjv-gqf2-c888","https://github.com/gardener/gardener/pull/15080","https://github.com/gardener/gardener/commit/63751db97dca6cc5ee5f966d4963415de6ae5545","https://github.com/gardener/gardener/releases/tag/v1.144.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-79767","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-79767","identifiers":["CVE-2026-79767"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
