Page Builder by SiteOrigin is installed on over 500,000 websites, and the issue affects versions up to 2.33.5. Attackers need only Contributor level access to exploit the local file inclusion vulnerability, which raises the risk profile. The fix arrives in version 2.34.0, so immediate updates or disabling the plugin are prudent, pragmatic steps.
