WordPress is not only the most popular script that we host, it is also most frequently targeted by attackers. While critical vulnerabilities in the WordPress core are relatively rare, they are fairly common in plugins and themes. It is important that these items are always kept updated to help prevent a compromise.
This can be a confusing process because the WP admin interface may not accurately portray certain situations. For example, if you’ve installed a plugin or theme outside of the WordPress repository, it may always show no updates being available even though that is not the case. The WP admin interface also doesn’t warn when something hasn’t received an update in a while, indicating it may no longer be actively maintained.
