Frontend File Manager Plugin

The Frontend File Manager Plugin WordPress plugin through 23.6 does not properly verify ownership of every targeted post before permanent deletion, allowing authenticated users with author-level access and above to permanently delete arbitrary posts and pages. When the Frontend File Manager Plugin WordPress plugin through 23.6's "Allow guest uploads" setting is enabled by an administrator, the same deletion primitive becomes reachable by unauthenticated users.

The Frontend File Manager Plugin WordPress plugin through 23.6 does not properly enforce its nonce check on the file download handler, allowing unauthenticated attackers to download files uploaded by any user through the Frontend File Manager Plugin WordPress plugin through 23.6 by iterating identifiers.

The Frontend File Manager Plugin WordPress plugin through 23.6 does not sanitise nor escape a filename submitted to the frontend file-rename endpoint before storing it as post meta and rendering it back on the admin File Manager listing, leading to a Stored Cross-Site Scripting vulnerability exploitable by users with Subscriber-level access and above against an administrator viewing the file management interface.

The Frontend File Manager Plugin WordPress plugin through 23.6 does not validate a file path derived from user input before deleting the referenced file, allowing unauthenticated users to delete arbitrary files on the server (such as wp-config.php) when guest upload mode is enabled. Deleting wp-config.php forces the site into its setup routine, which can be leveraged toward a full site takeover.

During the analysis, it was identified that authenticated attackers with Subscriber-level access or higher are able to perform an Insecure Direct Object Reference (IDOR) attack. This vulnerability exists because the Frontend File Manager Plugin WordPress plugin through 23.6 does not properly validate user authorization for the requested uploaded file when processing download requests. By modifying the value of the 'file_id' parameter in the download endpoint (e.g., http://localhost/?do=wpfm_download&file_id=40&nm_file_nonce=a36fb893f1), an attacker can access files belonging to other users, including privileged users such as administrators. This allows unauthorized access/read to sensitive data stored within the application.
