Upgrade typo3/cms-form to version 13.4.31, 14.3.3 or higher.
Overview
typo3/cms-form is a Form Library, Plugin and Editor
Affected versions of this package are vulnerable to Missing Authorization in the processing of form definition files by the Form Framework. An attacker can gain administrative privileges by uploading and using maliciously crafted files that are not restricted to the expected .form.yaml extension, which are then processed and can execute arbitrary SQL statements.
Note: This is only exploitable if the attacker is a backend user with access to the Form Framework.
