At a glance

CVE-2024-0903 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the UserFeedback WordPress plugin, affecting versions <= 1.0.13. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.0.14; sites on affected versions should update now. Disclosed February 2024, reported by Grzegorz Niedziela (gregxsunday).

Vulnerability Overview

The User Feedback – Create Interactive Feedback Form, User Surveys, and Polls in Seconds plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'page_submitted' 'link' value in all versions up to, and including, 1.0.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in the feedback submission page that will execute when a user clicks the link, while also pressing the command key.

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.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

UserFeedback <= 1.0.13 carries this weakness at page_submitted, and reaching it takes no account at all. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For UserFeedback the fix is 1.0.14: builds <= 1.0.13 are affected, anything from 1.0.14 onward is not.

Remediation

Update to version 1.0.14, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: UserFeedback 1.0.14 closes this, and updating the plugin is the step that ends it.
