The File Manager and File Manager Pro plugins for WordPress are vulnerable to Directory Traversal in versions up to, and including version 7.2.1 (free version) and 8.3.4 (Pro version) via the target parameter in the mkfilefoldermanageractioncallbackshortcode function. This makes it possible for attackers to read the contents of arbitrary files on the server, which can contain sensitive information and to upload files into directories other than the intended directory for file uploads. The free version requires Administrator access for this vulnerability to be exploitable. The Pro version allows a file manager to be embedded via a shortcode and also allows admins to grant file handling privileges to other user levels, which could lead to this vulnerability being exploited by lower-level users.

The File Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 7.2.4. This is due to missing or incorrect nonce validation on the wpfilemanager page that includes files through the 'lang' parameter. This makes it possible for unauthenticated attackers to include local JavaScript files that can be leveraged to achieve RCE via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This issue was partially patched in version 7.2.4, and fully patched in 7.2.5.

The File Manager WordPress plugin before 6.9.1 does not properly authorise its file management commands, allowing any authenticated user, such as a subscriber, to read and delete arbitrary files under the WordPress installation directory, which could lead to the disclosure of the site's configuration secrets and to denial of service.

Unrestricted file upload vulnerability in ajaxfilemanager.php in the Wp-FileManager 1.2 plugin for WordPress allows remote attackers to upload and execute arbitrary PHP code via unspecified vectors.

The File Manager plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 7.2.5 via the fmdownloadbackup function. This makes it possible for authenticated attackers, with administrator access and above, to read the contents of arbitrary zip files on the server, which can contain sensitive information.
