At a glance

CVE-2024-3600 is a high-severity Missing Authorization vulnerability in the Poll Maker by AYS WordPress plugin, affecting versions <= 5.1.8. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 5.1.9; sites on affected versions should update now. Disclosed April 2024, reported by Krzysztof Zając.

Vulnerability Overview

The Poll Maker – Best WordPress Poll Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to a missing capability check on the ays_poll_maker_quick_start AJAX action in addition to insufficient escaping and sanitization in all versions up to, and including, 5.1.8. This makes it possible for unauthenticated attackers to create quizzes and inject malicious web scripts into them that execute when a user visits the page.

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, and no interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in Poll Maker by AYS <= 5.1.8 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Poll Maker by AYS the fix is 5.1.9: builds <= 5.1.8 are affected, anything from 5.1.9 onward is not.

Remediation

Update to version 5.1.9, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Poll Maker by AYS 5.1.9 closes this, and updating the plugin is the step that ends it.
