According to Common Vulnerabilities and Exposures and The Free and Open Software Security Community here are the main current security issues with WordPress. The known issues are in plugins and one theme. The WordPress Application itself (the Core) does not have any know issues at this time. The plugin names in bold are ones I’ve used.
If you have any of these plugins, you should 1) backup your WordPress website (I use WP Updraft for that) then 2) update your plugins. If you use WP Like Button or One Signal you should remove these plugins and switch to something else.
