Contact Form Generator <= 2.5.5 - Cross-Site Scripting

id: CVE-2023-37988

info:
  name: Contact Form Generator <= 2.5.5 - Cross-Site Scripting
  author: 0xr2r,vats147
  severity: medium
  description: |
    The Contact Form Generator plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'id' parameter in wp-admin/admin.php in versions up to, and including, 2.5.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
  remediation: |
    Update to plugin version 2.5.6 or later.
