It is recommended that you update your WordPress application to the latest version, Wordpress 4.7.3. You can follow our documentation to learn how to upgrade your application and ensure its security.
For new application deployments, Bitnami has released WordPress 4.7.3 containers, installers, virtual machines and cloud images that address these vulnerabilities. If you deploy Bitnami WordPress via a Bitnami Launchpad, your application will be up-to-date and secure. If you deploy Bitnami WordPress via one of our cloud partner marketplaces and it is not yet updated to version 4.7.3, you will need to upgrade your application using the documentation linked above.
If you have further questions about Bitnami WordPress or this security issue, please post to our community forum, and we will be happy to help you.
