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)\n\n## Affected packages\n\n- `typo3/cms-core >= 14.0.0, < 14.3.3`\n- `typo3/cms-form >= 14.0.0, < 14.3.3`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `typo3/cms-core 14.3.3`\n- `typo3/cms-form 14.3.3`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
