Advisory Weakness Curation

TYPO3 CMS vulnerable to Arbitrary Code Execution via Form Framework ### Problem Due to the lack of separating user-submitted data from the internal configuration in the Form Designer backend module, it was 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 (known as `formDefinitionOverrides` https://docs.typo3.org/c/typo3/cms-form/main/en-us/I/Concepts/FrontendRendering/Index.html#form-element-properties) and a valid backend user account with access to the form module are needed to exploit this vulnerability. ### Solution Update to TYPO3 versions 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1 that fix the problem described above. ### References * TYPO3-CORE-SA-2022-015 https://typo3.org/security/advisory/typo3-core-sa-2022-015
