Maliciously crafted form definition files can be used to execute arbitrary SQL statements, allowing attackers to escalate privileges by creating administrative backend user accounts.\n\n### Solution\nUpdate to TYPO3 versions 10.4.57 ELTS, 11.5.51 ELTS, 12.4.46 ELTS, 13.4.31 LTS, 14.3.3 LTS that fix the problem described.\n\n### Credits\nTYPO3 CMS thanks “Ethan” for reporting this issue, and TYPO3 core & security team member Oliver Hader for fixing it.\n\n### Resources\n* [TYPO3-CORE-SA-2026-019](https://typo3.org/security/advisory/typo3-core-sa-2026-019)\n\n## Affected packages\n\n- `typo3/cms-core < 10.4.57`\n- `typo3/cms-core >= 11.0.0, < 11.5.51`\n- `typo3/cms-core >= 12.0.0, < 12.4.46`\n- `typo3/cms-core >= 13.0.0, < 13.4.31`\n- `typo3/cms-core >= 14.0.0, < 14.3.3`\n- `typo3/cms-form < 10.4.57`\n- `typo3/cms-form >= 11.0.0, < 11.5.51`\n- `typo3/cms-form >= 12.0.0, < 12.4.46`\n- `typo3/cms-form >= 13.0.0, < 13.4.31`\n- `typo3/cms-form >= 14.0.0, < 14.3.3`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `typo3/cms-core 10.4.57`\n- `typo3/cms-core 11.5.51`\n- `typo3/cms-core 12.4.46`\n- `typo3/cms-core 13.4.31`\n- `typo3/cms-core 14.3.3`\n- `typo3/cms-form 10.4.57`\n- `typo3/cms-form 11.5.51`\n- `typo3/cms-form 12.4.46`\n- `typo3/cms-form 13.4.31`\n- `typo3/cms-form 14.3.3`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
