Vulnerable plugins and themes are the #1 reason WordPress websites get hacked. The Weekly WordPress Vulnerability Report powered by WPScan covers recent WordPress plugin, theme, and core vulnerabilities, and what to do if you run one of the vulnerable plugins or themes on your website.

Each vulnerability will have a severity rating of Low, Medium, High, or Critical. Responsible disclosure and reporting of vulnerabilities is an integral part of keeping the WordPress community safe. Please share this post with your friends to help get the word out and make WordPress safer for everyone.

Is Your WordPress Website Secure?

DID YOU KNOW – A staggering 83% of WordPress websites are not upgraded or updated, is your website one of these?

Hacks happen due to lack of website upkeep and protection, like updating WordPress or plugins, plus using weak passwords. Contrary to popular belief, web designers and website hosting companies are not responsible for the security of your WordPress website; you are. It’s like using your computer without Anti-virus!
