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.
