Official Description

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

CVE-2014-0166 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

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.
