CVE-2022-4542Public exploitNetwork attack vector

Stored XSS via unescaped shortcode volume attribute

Published Jan 23, 2023 · Updated Apr 3, 2025

Stored XSS in Compact WP Audio Player before 1.9.8 allows remote authenticated users to run script in an administrator’s browser. The sc_embed_player shortcode inserts the volume attribute into the generated pause button without validation or output escaping, allowing an event-handler payload to persist in a post. Contributor access is sufficient to store the payload, and script executes when a higher-privileged user moves the pointer over the pause button.
