{"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":"2026-10-28T02:30:25.502616579Z","published":"2026-09-08T09:18:40.983Z","database_specific":{"cwe_ids":["CWE-266","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/85xxx/CVE-2026-85400.json","cna_assigner":"TYPO3"},"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":"cfda1147fba7bb5bbe30cf5aedd3277a0a329b3e"},{"fixed":"07f4dc8267d1824a3021c00cd36c5ad8ee7f84a1"},{"fixed":"b8abe36978c63a0625aee70df078895216e7ee27"},{"fixed":"e15da7ba0218532240578b471152f76c13cb4154"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"14.2.0"},{"fixed":"14.3.7"}],"source":"AFFECTED_FIELD"},{"range":[{"fixed":"b8abe36978c63a0625aee70df078895216e7ee27"}],"source":"REFERENCES_COMMIT"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"e15da7ba0218532240578b471152f76c13cb4154"}]}]}}],"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"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-85400.json"}}],"schema_version":"1.9.2","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"}]}
