## Technical details

The vulnerability is an Arbitrary File Read bug rooted in the get_files_for_attachment() function. When a client-supplied 'saveProgress' flag causes the process() method to return early, the plugin accepts a raw, attacker-controlled 'files' array. This bypasses standard upload validation, path normalization, and database record creation. An attacker can provide a specific 'file_path' value which is then passed to the WordPress wp_mail() function as an attachment after only a simple file_exists() check. This allows unauthenticated remote attackers to read any file on the server that the web server process has permissions to access.
