Description

The WP App Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'app-bar-features' parameter in all versions up to, and including, 1.5. This is due to insufficient input sanitization and output escaping combined with a missing authorization check in the `App_Bar_Settings` class constructor. This makes it possible for unauthenticated attackers to inject arbitrary web scripts into multiple plugin settings that will execute whenever a user accesses the admin settings page.

Analysis

Unauthenticated attackers can inject malicious scripts into WordPress sites running the WP App Bar plugin (versions up to 1.5) through the 'app-bar-features' parameter due to missing input validation and authorization checks. When site administrators access the plugin's settings page, the stored payload executes in their browser, enabling credential theft or unauthorized actions. …
