WordPress Plugin Vulnerabilities
AN_GradeBook <= 5.0.1 - Admin+ XSS
Description
The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
Proof of Concept
1. When adding a new course in the plugin settings, all fields are vulnerable to XSS with the payload: <script>alert('xss')</script>
2. Enter the payload into any field and reload the page to see XSS.
