CVE-2026-109513 · Severity: high · CVSS 7.2 · Published 2026-10-16

NotificationX is a WordPress plugin that adds notification banners and sales popups to e-commerce and content sites. The plugin fails to sanitize user input in the name parameter, allowing attackers to inject malicious scripts that execute when site visitors view affected pages. Exploitation requires that an administrator has already enabled a WordPress.org Reviews campaign and placed the notificationx dynamic block on a public page.
