CVE-2021-25088

Name of the Vulnerable Software and Affected Versions XML Sitemaps WordPress plugin versions prior to 4.1.3

Description The issue allows high privilege users to perform Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example in multisite setups. This is due to the plugin not sanitizing and escaping settings before outputting them in the Debug page.

Recommendations For versions prior to 4.1.3, update to version 4.1.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the Debug page to minimize the risk of exploitation.
