CVE-2026-85492
All in One SEO <= 5.0.1.1 - Reflected DOM-Based Cross-Site Scripting via URL Pathname
Description
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. Exploitation requires the victim to hold the aioseo_manage_seo capability and to open the SEO Preview panel in the WordPress admin toolbar while visiting a page with a malicious payload embedded in the URL pathname.
