            "summary": "Path Traversal\nDue to improper input validation, attackers can by-pass restrictions of predefined options and submit arbitrary data in the Form Designer backend module of the Form Framework. In the default configuration of the Form Framework this allows attackers to explicitly allow arbitrary mime-types for file uploads - however, default `_fileDenyPattern_` successfully blocked files like `_.htaccess_` or `_malicious.php_`. Besides that, attackers can persist those files in any writable directory of the corresponding TYPO3 installation. A valid backend user account with access to the form module is needed to exploit this vulnerability.",

Additionally, `_UploadedFileReferenceConverter_` transforming uploaded files into proper FileReference domain model objects handles possible file uploads for other extensions as well - given those extensions use the Extbase MVC framework, make use of FileReference items in their direct or inherited domain model definitions and did not implement their own type converter. In case this scenario applies, `_UploadedFileReferenceConverter_` accepts any file mime-type and persists files in the default location. In any way, uploaded files are placed in the default location `_/fileadmin/user_upload/_`, in most scenarios keeping the submitted filename - which allows attackers to directly reference files, or even correctly guess filenames used by other individuals, disclosing this information.
