{"id":"CVE-2025-59020","aliases":["GHSA-5j7q-wmh7-cqhg"],"url":"https://o3.security/vulnerability/CVE-2025-59020","summary":"TYPO3 CMS Allows Broken Access Control in Edit Document Controller","details":"### Problem\nBy exploiting the `defVals` parameter, attackers could bypass field‑level access checks during record creation in the TYPO3 backend. This gave them the ability to insert arbitrary data into prohibited exclude fields of a database table for which the user already has write permission for a reduced set of fields.\n\n### Solution\nUpdate to TYPO3 versions 10.4.55 ELTS, 11.5.49 ELTS, 12.4.41 LTS, 13.4.23 LTS, 14.0.2 that fix the problem described.\n\n### Credits\nThanks to Daniel Windloff for reporting this issue, and to TYPO3 core & security team member Benjamin Franzke for fixing it.\n\n### References\n* [TYPO3-CORE-SA-2026-001](https://typo3.org/security/advisory/typo3-core-sa-2026-001)","published":"2026-01-13T11:53:02.274Z","modified":"2026-08-27T03:30:39.587492692Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"typo3/cms-backend","fixedVersion":"14.0.2"},{"ecosystem":"Packagist","name":"typo3/cms-backend","fixedVersion":"13.4.23"},{"ecosystem":"Packagist","name":"typo3/cms-backend","fixedVersion":"12.4.41"},{"ecosystem":"Packagist","name":"typo3/cms-backend","fixedVersion":"11.5.49"},{"ecosystem":"Packagist","name":"typo3/cms-backend","fixedVersion":"10.4.55"}],"fix":{"url":"https://github.com/TYPO3/typo3/commit/ac3f792bd5ab7c58153fc1075cb9e001c9cebe3b","label":"TYPO3/typo3@ac3f792"},"references":[{"type":"WEB","url":"https://packagist.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59020.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59020"},{"type":"ADVISORY","url":"https://typo3.org/security/advisory/typo3-core-sa-2026-001"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/ac3f792bd5ab7c58153fc1075cb9e001c9cebe3b"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/cd11a19958d823d12d028f9345b41739c7e70118"},{"type":"FIX","url":"https://github.com/TYPO3/typo3/commit/fb98378a8fd30dd50d89a3d1a420780819f38232"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"},{"type":"WEB","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-5j7q-wmh7-cqhg"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:30:39.587492692Z"}}
