Since then a couple of updates have been made to the plugin, which may or may not be related to the closure. We didn’t see any obvious security changes in those updates, so we went to check to see if there were any obvious security issues that remain in the latest version, since we are interested in warning our customers if they are using vulnerable plugins.
