What is CVE-2025-13439?
CVE-2025-13439 is a medium-severity path traversal vulnerability in radykal Fancy Product Designer, published on 16 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Fancy Product Designer plugin for WordPress is vulnerable to Information Disclosure and PHAR Deserialization in all versions up to, and including, 6.4.8. This is due to insufficient validation of user-supplied input in the 'url' parameter of the 'fpd_custom_uplod_file' AJAX action, which flows directly into the 'getimagesize' function without sanitization. This makes it possible for unauthenticated attackers to read arbitrary sensitive files from the server, including wp-config.php.
Weakness: CWE-200
