The All in One SEO – AI SEO Plugin to Boost SEO Rankings & Traffic (Schema, Local SEO, Sitemap & SEO Insights) plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting via URL Pathname in all versions up to, and including, 5.0.1.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user visits a crafted URL.
