WordPress Plugin Vulnerabilities

Dropdown Menu Widget <= 1.9.7 - Subscriber+ Arbitrary Settings Update to Stored XSS

Description

The plugin does not have authorisation and CSRF checks when saving its settings, allowing low privilege users such as subscriber to update them. Due to the lack of sanitisation and escaping, it could also lead to Stored Cross-Site Scripting issues

Proof of Concept

Open the following URL as a subscriber: https://example.com/wp-admin/admin.php?shailan_dm_active_theme=*url*&shailan_dm_theme_url="><script>alert(/XSS/);</script>&action=save&page=dropdown-menu

You'll get a permission denied message. Ignore it and browse to https://example.com or the plugin's settings to trigger the XSS
