Is WP-BusinessDirectory safe? Known vulnerabilities and latest version

The WP-BusinessDirectory WordPress plugin through 4.0.2 does not restrict the type or destination of files saved by an unauthenticated upload handler, allowing unauthenticated attackers to write files with arbitrary content to arbitrary locations, though not to execute code on a default server configuration.

The WP-BusinessDirectory plugin for WordPress is vulnerable to Unauthenticated Arbitrary File Deletion in versions up to and including 4.0.1. This is due to insufficient path validation in the remove() method of the JBusinessDirectoryControllerUpload class. The task=upload.remove endpoint is accessible without authentication via the plugin's frontend routing system. The _filename parameter is accepted with RAW filter (no sanitization), and the helper function makePathFile() only normalizes directory separator characters without stripping path traversal sequences (../). When combined with the _path_type=2 parameter, which sets the base directory to the plugin's site folder, an attacker can supply a _filename value containing ../ sequences to traverse outside the plugin directory and call PHP's unlink() on arbitrary files — including wp-config.php, wp-config-backup.php, or other critical server files accessible to the web server process. This makes it possible for unauthenticated attackers to delete arbitrary files on the server.
