What is CVE-2025-10636?

The NS Maintenance Mode plugin for WordPress prior to version 1.3.1 has a vulnerability that stems from improper sanitization and escaping of certain settings. This flaw could potentially allow high-privilege users, like administrators, to execute stored cross-site scripting attacks, even when the unfiltered_html capability is turned off. This makes it particularly concerning in multisite configurations, where limitations on user capabilities are typically implemented to enhance security.

Affected Version(s)

NS Maintenance Mode for WP 0 <= 1.3.1
