What is CVE-2026-55116 and which devices are affected?

CVE-2026-55116 is a critical Improper Access Control vulnerability (CWE-284) impacting Ubiquiti UniFi OS devices running versions prior to 5.1.19. A remote, unauthenticated attacker can exploit this flaw under certain network configurations to make unauthorized changes to affected devices. Impacted product lines include Dream Machines, Enterprise Fortress Gateway, Dream Wall, Dream Routers, Express 7, Cloud Gateways, and Enterprise Firewall Core. Source: NIST, Ubiquiti SAB-066. Note: Only devices running UniFi OS prior to 5.1.19 are affected.

How can organizations mitigate CVE-2026-55116?

To mitigate CVE-2026-55116, upgrade all affected devices to UniFi OS version 5.1.19 or later. If immediate patching is not possible, restrict network access to UniFi OS management interfaces by placing devices behind a dedicated management VLAN or firewall rules that limit inbound access to trusted administrative hosts. These steps reduce the attack surface and limit exploitation risk. Note: Delaying patching increases exposure to active exploitation. Source: Ubiquiti SAB-066, Ionix Threat Center.

What is the severity and impact of CVE-2026-55116?

CVE-2026-55116 has a CVSS v3.1 base score of 9.0 (Critical). Successful exploitation allows an unauthenticated attacker to make arbitrary unauthorized changes to UniFi OS devices, resulting in full compromise of confidentiality, integrity, and availability. The vulnerability can lead to configuration manipulation, disruption of gateway and firewall functions, and lateral movement within connected networks. Note: Exploitation requires specific network conditions but no credentials or user interaction. Source: NIST, Ubiquiti SAB-066.

CVE-2026-55116 – Improper Access Control / Unauthorized Device Modification – Ubiquiti UniFi OS (…

Be the first to know when new zero-days emerge:

Summary

CVE-2026-55116 is a critical Improper Access Control vulnerability (CWE-284) affecting a wide range of devices running Ubiquiti UniFi OS, all versions prior to 5.1.19. A remote attacker with no prior authentication required can exploit this flaw under certain network configurations to make unauthorized changes to affected UniFi OS devices. Disclosed by Ubiquiti on July 2, 2026 via Security Advisory Bulletin 066 (SAB-066), the vulnerability carries a CVSS v3.1 base score of 9.0 (Critical) due to its potential for full confidentiality, integrity, and availability impact with a changed scope.

Technical details

  • Root cause: Improper access control (CWE-284) within the UniFi OS server component fails to enforce authorization checks under certain network configurations, permitting unauthorized actors to reach protected functionality.
  • Trigger conditions: Exploitation requires network access to the affected device and depends on specific network configurations being present; no credentials or user interaction are needed.
  • Attack vector: Network-accessible (AV:N); the attack can be initiated remotely. The High Attack Complexity (AC:H) rating reflects the requirement for particular network conditions to be met before exploitation is possible.
  • Impact: Successful exploitation allows an unauthenticated attacker to make arbitrary unauthorized changes to the UniFi OS device, resulting in full compromise of confidentiality (C:H), integrity (I:H), and availability (A:H) — including potential configuration manipulation, disruption of gateway and firewall functions, and lateral movement within connected networks. The Changed Scope (S:C) indicator means the impact can extend beyond the vulnerable component itself.

Affected software

All of the following Ubiquiti product lines are affected when running UniFi OS versions prior to 5.1.19:

  • Dream Machines
  • Enterprise Fortress Gateway
  • Dream Wall
  • Dream Routers
  • Express 7
  • Cloud Gateways
  • Enterprise Firewall Core

Severity

  • CVSS v3.1 Base Score: 9.0 (Critical)
  • Vector String: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate action — patch now: Upgrade all affected devices to UniFi OS version 5.1.19 or later, as released by Ubiquiti. Updates can be applied through the UniFi OS console management interface.
  • Network mitigation (if immediate patching is not possible): Restrict network access to UniFi OS management interfaces by placing affected devices behind a dedicated management VLAN or firewall rules that limit inbound access to trusted administrative hosts only. Reducing the attack surface by preventing arbitrary network paths to the device management plane limits the conditions under which this vulnerability can be exploited.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
