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. New in this report: vulnerabilities are now listed in order by the number of active installs, rather than the date of the disclosure.
Please share this post with your friends to help get the word out and make WordPress safer for everyone!
The latest version of WordPress core is 5.8.2. As a best practice, always be sure to run the latest version of WordPress core!
In this section, the latest WordPress plugin vulnerabilities have been disclosed. Each plugin listing includes the type of vulnerability, the active installations, the version number if patched, and the severity rating.
