Descriptions

Auth. (admin+) Cross-Site Scripting (XSS) vulnerability in Twardes Sitemap Index plugin <= 1.2.3 versions.

The Sitemap Index plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 1.2.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
