{"id":"GHSA-jh32-v29g-68pq","summary":"TYPO3 CMS has Privilege Escalation & SQL Injection in its Form Framework","details":"### Problem\nBackend users with write access to the `form_definition` database table were able to directly create, update, or delete form definition records via `DataHandler`, bypassing the Form Framework's persistence validation and permission checks. This allowed injecting arbitrary form configurations, re-enabling attack vectors originally addressed in [TYPO3-CORE-SA-2018-003](https://typo3.org/security/advisory/typo3-core-sa-2018-003), including SQL injection and privilege escalation.\n\n### Solution\nUpdate to TYPO3 version 14.3.3 LTS that fixes the problem described.\n\n### Credits\nTYPO3 CMS thanks Selçuk Güney for reporting this issue, and to TYPO3 core & security team member Oliver Hader for fixing it.\n\n### Resources\n* [TYPO3-CORE-SA-2026-017](https://typo3.org/security/advisory/typo3-core-sa-2026-017)","aliases":["CVE-2026-49741"],"modified":"2026-09-10T03:51:08.836282130Z","published":"2026-06-12T19:32:22Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-06-12T19:32:22Z","nvd_published_at":"2026-06-09T11:16:53Z","cwe_ids":["CWE-862","CWE-89"]},"references":[{"type":"WEB","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-jh32-v29g-68pq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49741"},{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/c90493c13b633f328cf2c066182c90a1655ff0fc"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms-core/CVE-2026-49741.yaml"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2018-003"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2026-017"}],"affected":[{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"14.0.0"},{"fixed":"14.3.3"}]}],"versions":["v14.0.0","v14.0.1","v14.0.2","v14.1.0","v14.1.1","v14.2.0","v14.3.0","v14.3.1","v14.3.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-jh32-v29g-68pq/GHSA-jh32-v29g-68pq.json"}},{"package":{"name":"typo3/cms-form","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-form"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"14.0.0"},{"fixed":"14.3.3"}]}],"versions":["v14.0.0","v14.0.1","v14.0.2","v14.1.0","v14.1.1","v14.2.0","v14.3.0","v14.3.1","v14.3.2"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-jh32-v29g-68pq/GHSA-jh32-v29g-68pq.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
