{"id":"GHSA-5j7q-wmh7-cqhg","aliases":["CVE-2025-59020"],"title":"TYPO3 CMS Allows Broken Access Control in Edit Document Controller","description":"### 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)","severity":"medium","score":5.3,"published":"2026-01-13T20:37:30.000Z","modified":"2026-02-03T02:59:49.378Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"typo3/cms-backend","ranges":[{"events":[{"introduced":"14.0.0"},{"fixed":"14.0.2"}],"type":"ECOSYSTEM"}],"versions":["v14.0.0","v14.0.1"],"fixed":["14.0.2"]},{"ecosystem":"Packagist","name":"typo3/cms-backend","ranges":[{"events":[{"introduced":"13.0.0"},{"fixed":"13.4.23"}],"type":"ECOSYSTEM"}],"versions":["v13.0.0","v13.0.1","v13.1.0","v13.1.1","v13.2.1","v13.3.0","v13.3.1","v13.4.0","v13.4.1","v13.4.10","v13.4.11","v13.4.12","v13.4.13","v13.4.14","v13.4.15","v13.4.16","v13.4.17","v13.4.18","v13.4.19","v13.4.2","v13.4.20","v13.4.21","v13.4.22","v13.4.3","v13.4.4","v13.4.5","v13.4.6","v13.4.7","v13.4.8","v13.4.9"],"fixed":["13.4.23"]},{"ecosystem":"Packagist","name":"typo3/cms-backend","ranges":[{"events":[{"introduced":"12.0.0"},{"fixed":"12.4.41"}],"type":"ECOSYSTEM"}],"versions":["v12.0.0","v12.1.0","v12.1.1","v12.1.2","v12.1.3","v12.2.0","v12.3.0","v12.4.0","v12.4.1","v12.4.10","v12.4.11","v12.4.12","v12.4.13","v12.4.14","v12.4.15","v12.4.16","v12.4.17","v12.4.18","v12.4.19","v12.4.2","v12.4.20","v12.4.21","v12.4.22","v12.4.23","v12.4.24","v12.4.25","v12.4.26","v12.4.27","v12.4.28","v12.4.29","v12.4.3","v12.4.30","v12.4.31","v12.4.32","v12.4.33","v12.4.34","v12.4.35","v12.4.36","v12.4.37","v12.4.38","v12.4.39","v12.4.4","v12.4.40","v12.4.5","v12.4.6","v12.4.7","v12.4.8","v12.4.9"],"fixed":["12.4.41"]},{"ecosystem":"Packagist","name":"typo3/cms-backend","ranges":[{"events":[{"introduced":"11.0.0"},{"fixed":"11.5.49"}],"type":"ECOSYSTEM"}],"versions":["v11.0.0","v11.1.0","v11.1.1","v11.2.0","v11.3.0","v11.3.1","v11.3.2","v11.3.3","v11.4.0","v11.5.0","v11.5.1","v11.5.10","v11.5.11","v11.5.12","v11.5.13","v11.5.14","v11.5.15","v11.5.16","v11.5.17","v11.5.18","v11.5.19","v11.5.2","v11.5.20","v11.5.21","v11.5.22","v11.5.23","v11.5.24","v11.5.25","v11.5.26","v11.5.27","v11.5.28","v11.5.29","v11.5.3","v11.5.30","v11.5.31","v11.5.32","v11.5.33","v11.5.34","v11.5.35","v11.5.36","v11.5.37","v11.5.38","v11.5.39","v11.5.4","v11.5.40","v11.5.41","v11.5.5","v11.5.6","v11.5.7","v11.5.8","v11.5.9"],"fixed":["11.5.49"]},{"ecosystem":"Packagist","name":"typo3/cms-backend","ranges":[{"events":[{"introduced":"10.0.0"},{"fixed":"10.4.55"}],"type":"ECOSYSTEM"}],"versions":["v10.0.0","v10.1.0","v10.2.0","v10.2.1","v10.2.2","v10.3.0","v10.4.0","v10.4.1","v10.4.10","v10.4.11","v10.4.12","v10.4.13","v10.4.14","v10.4.15","v10.4.16","v10.4.17","v10.4.18","v10.4.19","v10.4.2","v10.4.20","v10.4.21","v10.4.22","v10.4.23","v10.4.24","v10.4.25","v10.4.26","v10.4.27","v10.4.28","v10.4.29","v10.4.3","v10.4.30","v10.4.31","v10.4.32","v10.4.33","v10.4.34","v10.4.36","v10.4.37","v10.4.4","v10.4.5","v10.4.6","v10.4.7","v10.4.8","v10.4.9"],"fixed":["10.4.55"]}],"sourceAffected":[],"references":["https://github.com/TYPO3/typo3/security/advisories/GHSA-5j7q-wmh7-cqhg","https://nvd.nist.gov/vuln/detail/CVE-2025-59020","https://github.com/TYPO3/typo3/commit/ac3f792bd5ab7c58153fc1075cb9e001c9cebe3b","https://github.com/TYPO3/typo3/commit/cd11a19958d823d12d028f9345b41739c7e70118","https://github.com/TYPO3/typo3/commit/fb98378a8fd30dd50d89a3d1a420780819f38232","https://github.com/TYPO3/typo3","https://typo3.org/security/advisory/typo3-core-sa-2026-001"],"sources":[{"name":"OSV","id":"GHSA-5j7q-wmh7-cqhg","modified":"2026-02-03T02:59:49.378236Z","url":"https://osv.dev/vulnerability/GHSA-5j7q-wmh7-cqhg"}],"assessments":[{"source":"OSV","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:L","score":5.3}]}
