At a glance

CVE-2024-13753 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Ultimate Classified Listings WordPress plugin, affecting versions <= 1.5. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high confidentiality, integrity impact). Exploitation requires no authentication. The issue is fixed in version 1.6; sites on affected versions should update now. Disclosed February 2025, reported by Rob Banks.

Vulnerability Overview

The Ultimate Classified Listings plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5. This is due to missing or incorrect nonce validation on the update_profile function. This makes it possible for unauthenticated attackers to modify victim's email via a forged request, which might lead to account takeover, granted they can trick a user into performing an action such as clicking on a link.

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 privileges on the target site. A successful exploit has high impact on confidentiality, integrity.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Ultimate Classified Listings <= 1.5 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Ultimate Classified Listings the fix is 1.6: builds <= 1.5 are affected, anything from 1.6 onward is not.

Remediation

Update to version 1.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Ultimate Classified Listings: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Ultimate Classified Listings 1.6 closes this, and updating the plugin is the step that ends it.
