The WordPress File Upload plugin is vulnerable due to improper input validation in the wfu_file_downloader.php file, affecting versions <= 4.24.11. This vulnerability allows unauthenticated users to download arbitrary files from the server's filesystem, leading to potential data exfiltration and system compromise.
Websites running WordPress with the File Upload Plugin version <= 4.24.11.
The vulnerability resides in the wfu_file_downloader.php component of the File Upload Plugin, which mishandles the file and handler parameters in its requests. This allows directory traversal attacks to access sensitive files.
