CVE-2026-93896

WPFront Notification Bar <= 3.5.1 - Reflected Cross-Site Scripting via REQUEST_URI

The WPFront Notification Bar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 3.5.1. This is due to the debug-log output path (write_debug_logs) reflecting the raw value of $_SERVER['REQUEST_URI'] through vprintf() directly inside a <script> block emitted on wp_footer, without any sanitization or escaping (see the 'Current URL is "%s"' log entry produced by the URL-text display filter in the filter() method). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link.

WPFront Notification Bar <= 3.3.2 - Authenticated (Admin+) Stored Cross-Site Scripting via wpfront-notification-bar-options[custom_class]

The WPFront Notification Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘wpfront-notification-bar-options[custom_class]’ parameter in all versions up to, and including, 3.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, 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.

WPFront Notification Bar < 2.1.0.08087 - Authenticated Stored XSS

The WPFront Notification Bar WordPress plugin before 2.1.0.08087 does not properly sanitise and escape its settings, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
