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
files on the server, disclose private information, create open
redirects, poison cache, and bypass authorization access and input
sanitation.

For the oldstable distribution (stretch), these problems have been fixed
in version 4.7.5+dfsg-2+deb9u6.

For the stable distribution (buster), these problems have been fixed in
version 5.0.4+dfsg1-1+deb10u2.

We recommend that you upgrade your wordpress packages.
