CVE-2022-4718Public exploitNetwork attack vector

Stored XSS via unescaped shortcode logo URL

Published Jan 23, 2023 · Updated Apr 3, 2025

Stored XSS in PluginOps Landing Page Builder before 1.4.9.9 allows remote authenticated users to execute script in an administrator's browser. The pb_samlple_nav shortcode writes its pb_logo_url attribute into page output without validation or escaping, so a quote can inject an onerror handler. Contributor access is sufficient to save the crafted shortcode; the script executes when a privileged user views the affected page and can act in that browser session.
