CVE-2026-77535Network attack vector

Command execution on adopted devices

Published Aug 26, 2026 · Updated Aug 26, 2026

Command injection in Ubiquiti UniFi Network Application before 10.5.67 allows remote authenticated users to execute commands on adopted devices. Ubiquiti attributes the flaw to improper input validation but has not disclosed the affected request, parameter, function, or code path. Network access, high application privileges, and an adopted device are required; successful exploitation compromises that managed device's confidentiality, integrity, and availability.
