Summary
CVE-2026-1680 is a high-severity Execution with Unnecessary Privileges (CWE-250) vulnerability in Danofficeit Local Admin Service. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 0.9th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-1680, published on 2026-01-30, is an improper access control vulnerability in the WCF endpoint of Edgemo (now owned by Danoffice IT) Local Admin Service version 1.2.7.23180 on Windows. The issue resides in the LocalAdminService.exe named pipe, which fails to enforce client-side group membership restrictions, enabling unauthorized privilege escalation.
A local user with low privileges (PR:L) can exploit this vulnerability with low attack complexity (AC:L) and no user interaction (UI:N) by directly communicating with the named pipe. Successful exploitation allows the attacker to elevate privileges to local administrator, resulting in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), as reflected in the CVSS 3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The vulnerability is linked to CWE-250 and NVD-CWE-Other.

Mitigating Controls (NIST 800-53 r5) AI
Directly mandates enforcement of approved authorizations for access to system resources like named pipes, addressing the improper access control that bypasses group membership restrictions.
Employs least privilege to restrict processes like LocalAdminService.exe to minimal necessary access, limiting the impact of privilege escalation even if enforcement fails.
Requires timely identification, reporting, and correction of flaws such as this improper access control vulnerability in LocalAdminService.exe version 1.2.7.23180.
