Several vulnerabilities were discovered in Wordpress, a web blogging tool. They allowed remote attackers to perform various Cross-Side Scripting (XSS) and Cross-Site Request Forgery (CSRF) attacks, create open redirects, poison cache, and bypass authorization access and input sanitation.
For the stable distribution (buster), these problems have been fixed in version 5.0.4+dfsg1-1+deb10u1.
We recommend that you upgrade your wordpress packages.
