What is CVE-2025-13231?
CVE-2025-13231 is a medium-severity server-side request forgery 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 Server-Side Request Forgery in all versions up to, and including, 6.4.8. This is due to a time-of-check/time-of-use (TOCTOU) race condition in the 'url' parameter of the fpd_custom_uplod_file AJAX action. The plugin validates the URL by calling getimagesize() first, then later retrieves the same URL using file_get_contents(). This makes it possible for unauthenticated attackers to exploit the timing gap to perform SSRF attacks by serving a valid image during validation, then changing the response to redirect to arbitrary internal or external URLs during the actual fetch.
