WP Security bulletin – April 2019

Wait… what? April? Yes, you read correctly. There was quite a bit of drama involved with several big names, affecting a lot of online WordPress sites. We offered time to clear their names and to patch up their “not guilty until proven otherwise” code. Unfortunately, its the otherwise case. “It is nice to be important, but it’s more important to be nice.”

At your next scheduled WordPress Maintenance, be advised for your WP Security about the latest 14 vulnerabilities in WordPress plugins identified and reported publicly in April 2019. As these vulnerabilities are disclosed, when you use one (or more) of these outdated plugins – your risking serious WordPress breaches to your site(s).
