Input passed to the "forwarder" parameter is not properly sanitised. This can be exploited to inject malicious characters into HTTP headers and may allow execution of arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerability has been confirmed in version 7.5. Other versions may also be affected.
