CVE-2026-1680Public exploit

Local privilege escalation via unchecked WCF request

Published Jan 30, 2026 · Updated Jan 30, 2026

Improper access control in the WCF endpoint of Danoffice IT Local Admin Service 1.2.7.23180 allows local users to gain administrator rights. The SYSTEM service accepts Elevate calls on net.pipe://localhost/Elevation without repeating the client's RestrictionGroup membership check. Any local low-privileged account can use a custom WCF client to join the local Administrators group, gaining full control of the Windows host.
