Administrator-level stored XSS via unescaped Sitemap URL

Published Jun 5, 2023 · Updated Feb 13, 2025

Stored XSS in SEO by 10Web before 1.2.7 allows remote authenticated users with administrator privileges to execute script in a browser. The Sitemap settings accept a crafted new-URL value and persist it without sanitizing input or escaping it when rendered. The flaw is reachable when an administrator lacks unfiltered_html, such as on WordPress multisite, and the stored script runs when the affected page is accessed.
