Incorrect Authorization

CVE-2025-59020

Medium
5.3/10

Summary

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. This issue affects TYPO3 CMS versions 10.0.0 through 10.4.54, 11.0.0 through 11.5.48, 12.0.0 through 12.4.40, 13.0.0 through 13.4.22 and 14.0.0 through 14.0.1.

CWE-863 - Incorrect Authorization

Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
