Title
XenForo Template Method Call Restriction Bypass
Summary
XenForo before 2.3.7 does not properly restrict methods callable from within templates. A loose prefix match was used instead of a stricter first-word match for methods accessible through callbacks and variable method calls in templates, potentially allowing unauthorized method invocations.

Title
XenForo Open Redirect via getDynamicRedirect
Summary
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.
