WordPress Plugin Vulnerabilities
WPFront Notification Bar < 2.0.0.07176 - Authenticated Stored XSS
Description
The plugin does not sanitise or escape its Custom CSS setting, allowing high privilege users such as admin to set XSS payload in it even when the unfiltered_html capability is disallowed, leading to an authenticated Stored Cross-Site Scripting issue
Proof of Concept
v < 1.9.2.07163 - Put the following payload in the Custom CSS setting (wp-admin/options-general.php?page=wpfront-notification-bar) of the plugin: </textarea><script>alert(/XSS/)</script> v < 2.0.0.07176 - Use the following payload: </style><script>alert(/XSS/)</script>
