Yuzo Related Posts <= 5.12.93 - Missing Authorization to Stored Cross-Site Scripting

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2019-11869
CVSS High (7.2)
Publicly Published April 10, 2019
Last Updated January 22, 2024
Researcher Daniel van Dorp
Description

The Yuzo Related Posts plugin 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.
