CVE-2022-1961Network attack vector

Stored XSS via unescaped scroller content ID

Published Jun 13, 2022 · Updated Apr 8, 2026

Stored XSS in Thomas Geiger Google Tag Manager for WordPress 1.15.1 and earlier allows remote authenticated users to inject scripts. The public/frontend.php code insufficiently escapes the stored gtm4wp-options[scroller-contentid] setting before placing it in generated pages. Administrator access and a multisite or other configuration that disables unfiltered_html are required, and the injected script runs in browsers that load the affected output.
