A malicious actor with access to the network and under certain network configurations could exploit an Improper Access Control vulnerability found in certain devices running UniFi OS to make unauthorized changes to such UniFi OS devices.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-55116) involves improper access control (CWE-284) in Ubiquiti Inc Dream Machines running UniFi OS. An attacker with network access, depending on network configuration, may exploit this issue to perform unauthorized modifications on the device. The CVSS 3.1 vector indicates network attack vector with high attack complexity, no privileges required, no user interaction, and a scope change resulting in high confidentiality, integrity, and availability impacts. No official remediation or patch information is currently available.
Potential Impact
Successful exploitation allows an unauthenticated attacker on the network to make unauthorized changes to UniFi OS devices, potentially compromising device confidentiality, integrity, and availability. This could lead to full control over the affected device and disruption of its normal operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to UniFi OS devices and review network configurations to reduce exposure. Monitor vendor communications for updates.
