At a glance

CVE-2025-13393 is a medium-severity Server-Side Request Forgery (SSRF) vulnerability in the Featured Image from URL (FIFU) WordPress plugin, affecting versions <= 5.3.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 5.3.2; sites on affected versions should update now. Disclosed January 2026, reported by Dmitrii Ignatyev.

Vulnerability Overview

The Featured Image from URL (FIFU) plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 5.3.1. This is due to insufficient validation of user-supplied URLs before passing them to the getimagesize() function in the Elementor widget integration. This makes it possible for authenticated attackers, with Contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services via the fifu_input_url parameter in the FIFU Elementor widget granted they have permissions to use Elementor.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-918: Server-Side Request Forgery (SSRF)

Featured Image from URL (FIFU) <= 5.3.1 carries this weakness at getimagesize(), and reaching it takes an account at Contributor level or above. Server-side request forgery means the application fetches a URL supplied by the caller, turning the server into a proxy for requests the attacker could not make directly.

The request originates from inside the hosting network, which is how these flaws reach cloud metadata endpoints, internal admin panels and services that trust local traffic. For Featured Image from URL (FIFU) the fix is 5.3.2: builds <= 5.3.1 are affected, anything from 5.3.2 onward is not.

Remediation

Update to version 5.3.2, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Featured Image from URL (FIFU) 5.3.2 closes this, and updating the plugin is the step that ends it.
