The wp_validate_auth_cookie function in wp-includes/pluggable.php in WordPress before 3.7.2 and 3.8.x before 3.8.2 does not properly determine the validity of authentication cookies, which makes it easier for remote attackers to obtain access via a forged cookie.
Technical Analysis

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
