Fedora 31: FEDORA-2019-f21ad78845 Moderate: WordPress XSS Attacks

Wordpress is an online publishing / weblog package that makes it very easy,

almost trivial, to get information out to people on the web.

Important information in /usr/share/doc/wordpress/README.fedora

**WordPress 5.2.4 Security Release** WordPress versions 5.2.3 and earlier are

affected by these bugs, which are fixed in version 5.2.4. **Security Updates**

* Props to Evan Ricafort for finding an issue where stored XSS (cross-site

scripting) could be added via the Customizer. * Props to J.D. Grimes who

found and disclosed a method of viewing unauthenticated posts. * Props to

Weston Ruter for finding a way to create a stored XSS to inject Javascript into

style tags. * Props to David Newman for highlighting a method to poison the

cache of JSON GET requests via the Vary: Origin header. * Props to Eugene

Kolodenker who found a server-side request forgery in the way that URLs are

validated. * Props to Ben Bidner of the WordPress Security Team who

discovered issues related to referrer validation in the admin.
