{"id":"CVE-2026-85400","summary":"TYPO3 CMS - Missing Authorization in lowlevel commands","details":"Backend administrators without system maintainer privileges were able to schedule any of the configuration:read, configuration:set, and configuration:show commands. This allowed them to modify arbitrary system configuration, which is normally limited to system maintainers. As a consequence, this allowed them, for example, to gain system maintainer privileges or cause a denial of service. Exploiting this vulnerability requires an administrator-level backend user account. This issue affects TYPO3 CMS versions 14.2.0-14.3.6.","modified":"2026-09-10T03:48:35.077260995Z","published":"2026-09-08T09:18:40.983Z","database_specific":{"cna_assigner":"TYPO3","cwe_ids":["CWE-266","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85400.json","unresolved_ranges":[{"extracted_events":[{"introduced":"14.2.0"},{"fixed":"14.3.7"}],"source":"AFFECTED_FIELD"},{"extracted_events":[{"introduced":"14.2.0"},{"fixed":"14.3.7"}],"source":"CPE_FIELD"}]},"references":[{"type":"WEB","url":"https://packagist.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85400.json"},{"type":"ADVISORY","url":"https://news.typo3.com/security/advisory/typo3-core-sa-2026-023"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-85400"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/b8abe36978c63a0625aee70df078895216e7ee27"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/e15da7ba0218532240578b471152f76c13cb4154"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/typo3/typo3","events":[{"introduced":"0"},{"fixed":"b8abe36978c63a0625aee70df078895216e7ee27"},{"fixed":"e15da7ba0218532240578b471152f76c13cb4154"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v14.3.6","v14.3.5","v14.3.4","v14.3.3","v14.3.2","v14.3.1","v14.3.0","v14.2.0","v14.1.0","v14.0.0","v13.4.0","v13.3.0","v13.2.1","v13.2.0","v13.1.0","v13.0.0","v12.4.0","v12.3.0","v12.2.0","v12.1.0","v12.0.0","v11.5.3","v11.5.2","v11.5.1","v11.5.0","v11.4.0","v11.3.0","v11.2.0","v11.1.0","v11.0.0","v10.4.3","v10.4.2","v10.4.1","v10.4.0","v10.3.0","v10.2.0","v10.1.0","v10.0.0","v9.5.3","v9.5.2","v9.5.1","v9.5.0","v9.4.0","v9.3.0","v9.2.0","v9.1.0","v9.0.0","TYPO3_8-7-0","8.7.0","TYPO3_8-6-0","8.6.0","TYPO3_8-5-0","8.5.0","TYPO3_8-4-0","8.4.0","TYPO3_8-3-0","8.3.0","TYPO3_8-2-0","8.2.0","TYPO3_8-1-0","8.1.0","TYPO3_8-0-0","8.0.0","TYPO3_7-6-2","7.6.2","TYPO3_7-6-1","7.6.1","TYPO3_7-6-0","7.6.0","TYPO3_7-5-0","7.5.0","TYPO3_7-4-0","7.4.0","TYPO3_7-3-0","7.3.0","TYPO3_7-2-0","7.2.0","TYPO3_7-1-0","7.1.0","TYPO3_7-0-0","7.0.0","TYPO3_6-2-3","6.2.3","TYPO3_6-2-2","6.2.2","TYPO3_6-2-1","6.2.1","TYPO3_6-2-0","6.2.0","TYPO3_6-2-0rc2","TYPO3_6-2-0rc1","TYPO3_6-2-0beta7","TYPO3_6-2-0beta6","TYPO3_6-2-0beta5","TYPO3_6-2-0beta4","TYPO3_6-2-0beta3","TYPO3_6-2-0beta2","TYPO3_6-2-0beta1","TYPO3_6-2-0alpha3","TYPO3_6-2-0alpha2","TYPO3_6-2-0alpha1","TYPO3_6-1-0rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85400.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
