Emlog is an open source website building system. Prior to version 2.6.16, Emlog CMS Pro contains a blind SQL injection in User_Model::getUserDataByLogin(). The $account parameter is directly interpolated into SQL queries without any filtering. The vulnerability is reachable through the auth cookie validation path, where $username is extracted from the cookie and passed unfiltered into SQL — guarded only by an HMAC signature that requires AUTH_KEY to forge. This issue has been patched in version 2.6.16.
