What the vulnerability does
01Description
The JKDEVKIT plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'font_upload_handler' function in all versions up to, and including, 1.9.4. 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). If WooCommerce is enabled, attackers will need Contributor-level access and above.

An attacker with low-level access can bypass directory restrictions and access sensitive files outside the intended application directory. This affects confidentiality, integrity, and availability of the entire system.
