SiteSEO – SEO Simplified <= 1.3.1 - Missing Authorization to Authenticated (Author+) Plugin Settings Update

Published Nov 1, 2025 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The SiteSEO – SEO Simplified plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.3.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with Author-level access and above, to enable or disable arbitrary SiteSEO features that they should not have access to.
