The WordPress security team tried to mitigate all vulnerabilities without any back-compat breaks, but unfortunately there were a few cases where that was not possible. Plugin authors are encouraged to read the 5.0.1 developer notes for information on backwards-compatibility.
We have released Bitnami WordPress 5.0.1 (and Multisite version) installers, virtual machines and cloud images for all platforms as well as the WordPress containers and Helm Charts to deploy this version in Kubernetes.
WordPress already supports the auto-upgrade functionality. For minor versions like the current one, an already existing WordPress 5.0 has been automatically updated. If that was not the case, you can follow our docs for upgrading your WordPress installation.
Have questions about Bitnami WordPress or the security issue? Post to our community forum, and we would be happy to help you.
