CVE-2022-4005Public exploitNetwork attack vector

Stored XSS via unescaped shortcode align attribute

Published Dec 12, 2022 · Updated Apr 22, 2025

Stored XSS in MBJ Webdevelopment Donation Button 4.0.0 and earlier allows remote authenticated users to execute JavaScript via a crafted shortcode. The paypal_donation_button shortcode writes the align attribute into rendered HTML without context-appropriate escaping, so a quote terminates the attribute and injects an event handler. Contributor access is sufficient to store the payload in a post; JavaScript executes when another user views the rendered button.
