Description
ZenTao PMS before 22.3 contains an authorization bypass vulnerability in commonModel::isOpenMethod() that lets logged-in users skip group-based ACL checks for any method containing 'ajax'. Minimal-privilege users can call methods like task.ajaxGetByID, system.ajaxDBAuthUrl and admin.ajaxChangeTableEngine to read data, obtain database credentials, trigger CI jobs and alter tables.
