Technical details
The Page Builder by SiteOrigin plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the 'panels_data' parameter. The vulnerability exists because the plugin fails to sufficiently sanitize input and escape output when handling post metadata. Authenticated attackers with Contributor-level permissions can bypass standard WordPress 'unfiltered_html' restrictions because the data is stored as post meta, which does not trigger the 'wp_kses' fallback. This allows the injection of arbitrary web scripts (such as via WP_Widget_Custom_HTML content) that execute when a user views the compromised page. The issue is present in all versions up to and including 2.34.3.
