Sources and claim methodology

  • Source referencewpscan.com
Upstream source description

The Ajaxify Comments WordPress plugin before 3.2 is vulnerable to HTTP Header Injection due to insufficient input sanitization and output escaping on user-supplied data. This makes it possible for unauthenticated attackers to inject arbitrary HTTP headers.
