Detailsinfo

A vulnerability classified as critical has been found in wpmudev Forminator Forms Plugin up to 1.52.1 on WordPress. Affected is the function file_path of the component File Upload. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. CVE summarizes:

Successful exploitation requires a publicly accessible form with a File Upload field where Save and Continue is enabled in that form's Behavior settings and the Save and Continue email notification is configured to attach uploaded files in Email Notifications.
