What the vulnerability does
01Description
The Experto Dashboard for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's settings fields (including 'Navigation Font Size', 'Navigation Font Weight', 'Heading Font Size', 'Heading Font Weight', 'Text Font Size', and 'Text Font Weight') in all versions up to and including 1.0.4. This is due to insufficient input sanitization (no sanitize callback in register_setting()) and missing output escaping (no esc_attr() in the field_callback() printf output) on user-supplied values. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in the plugin settings page that will execute whenever a user accesses the settings page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
