TYPO3 is an open source PHP based web content management system. Versions
prior to 8.7.49, 9.5.38, 10.4.33, 11.5.20, and 12.1.1 are vulnerable to
Code Injection. Due to the lack of separating user-submitted data from the
internal configuration in the Form Designer backend module, it is possible
to inject code instructions to be processed and executed via TypoScript as
PHP code. The existence of individual TypoScript instructions for a
particular form item and a valid backend user account with access to the
form module are needed to exploit this vulnerability. This issue is patched
in versions 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1.
