CVE-2022-23503

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
