CVE-2026-110506 · Severity: info · Published 2026-10-28

The Page Builder by SiteOrigin is a WordPress plugin that allows users to design page layouts visually. The plugin fails to properly sanitize user input in widget properties, allowing contributors and higher-privileged users to inject malicious code that executes when administrators or editors view the page in the editor. An attacker with contributor access could compromise accounts of higher-privileged administrators through this stored attack.

## Technical details

A stored cross-site scripting (XSS) vulnerability exists in the panels_info.class component due to insufficient sanitization and escaping of widget properties before output in the page builder interface. The vulnerability requires an attacker to have at least contributor role access to craft and store a malicious payload. When a higher-privileged user (editor or administrator) opens the affected post in the editor, the stored payload executes in their browser context.
