Certighost (CVE-2026-54121)

Authors: @h0j3n, @aniqfakhrul
Date: July 24, 2026

---

Certighost is an Active Directory Certificate Services (AD CS) vulnerability that allowed a low-privileged domain user to impersonate a Domain Controller and achieve domain compromise in the tested AD CS configuration. The issue was addressed in the July 2026 security updates.

The vulnerable path is an AD CS enrollment fallback known as a chase during directory-object resolution. By supplying request attributes such as cdc, an attacker could cause the Certification Authority (CA) to ask an attacker-controlled host for identity data belonging to a Domain Controller. The CA then used that data while issuing a certificate.
