CVE-2022-3830Network attack vector

Admin-level stored XSS via unescaped plugin settings

Published Dec 5, 2022 · Updated Apr 24, 2025

Stored XSS in Themeum WP Page Builder 1.2.8 and earlier allows remote authenticated users to inject scripts through plugin settings. The settings path stores values without sufficient input sanitization or output escaping, causing attacker-supplied JavaScript to execute when a user opens an injected page. Administrator privileges are required, and exposure remains relevant when unfiltered_html is disabled, including in WordPress multisite.
