Specifically, these endpoints do not correctly validate user credentials, allowing attackers to <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-26438-bypassing-smp-authentication-for-possible-remote-privilege-escalation\/\"  data-wpil-monitor-id=\"87059\">bypass the standard authentication<\/a> processes.
