What the vulnerability does
01Description
The WooCommerce Support Ticket System plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_uploaded_file() function in all versions up to, and including, 17.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

An attacker can navigate outside intended directories to access sensitive data, configuration files, or system files. This affects all versions up to 17.7. Update to a version newer than 17.7 to remediate.
