Earlier this week, a critical vulnerability was patched in the Profile Builder plugin for WordPress. This vulnerability affected the free version available on the WordPress.org repository, as well as the commercial Pro and Hobbyist variants. According to the WordPress repository more than 50,000 sites are running the free version of Profile Builder, and our estimates suggest there are roughly 15,000 installations of the Pro and Hobbyist versions, for an estimated total of 65,000 affected sites.
