Description

XenForo before 2.2.17 and 2.3.1 allows open redirect via a specially crafted URL. The getDynamicRedirect() function does not adequately validate the redirect target, allowing attackers to redirect users to arbitrary external sites using crafted URLs containing newlines, user credentials, or host mismatches.
