Last modified

CVE-2025-59020 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. By 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. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
