Exploit for WordPress Yuzo <5.12.94 - Cross-Site Scripting (CVE-2019-11869)

Description:

WordPress Yuzo Related Posts plugin before 5.12.94 is vulnerable to cross-site scripting because it mistakenly expects that is_admin() verifies that the request comes from an admin user (it actually only verifies that the request is for an admin page). An unauthenticated attacker can consequently inject a payload into the plugin settings, such as the yuzo_related_post_css_and_style setting.
