The Page Builder by SiteOrigin WordPress plugin before 2.38.0 does not sanitize or escape a widget property before storing it and outputting it in the page builder interface, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks against higher-privileged users who open the affected post in the editor.
