Technical details
The cot_url_check() function uses a regular expression lacking an end-of-string anchor to validate redirect destinations, allowing bypass via hostnames prefixed with the legitimate site domain. The ratings plugin and other redirect callers are vulnerable to this flaw. An attacker-supplied hostname starting with the expected domain will pass validation but redirect to an attacker-controlled host.
