- Limit access to plugin-related content management to trusted users.
Validation and detection
- Confirm whether WP Bakery Autoresponder Addon is installed.
- Record the installed plugin version on each WordPress site.
- Treat versions 1.0.6 and earlier as affected per the CVE description.
- Review Patchstack and CVE records for updated remediation details.
- Verify remediation by confirming the plugin is upgraded, disabled, or removed.
