Vulnerability Overview
The Drag and Drop Multiple File Upload PRO plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 2.10.9 due to insufficient restrictions on the path supplied to the upload_dir value.

Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in Drag and Drop Multiple File Upload PRO - Contact Form 7 Standard <= 2.10.9 takes a caller who can reach the endpoint. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Drag and Drop Multiple File Upload PRO - Contact Form 7 Standard the fix is 2.11.0: builds <= 2.10.9 are affected, anything from 2.11.0 onward is not.
Remediation
Update to version 2.11.0, or a newer patched version
