Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Directly enforces approved authorizations for logical access, preventing unauthorized network users from obtaining sensitive UniFi Play WiFi credentials due to improper access controls.

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of flaws like this improper access control vulnerability through software updates to fixed versions.

AC-6 Least Privilege partial match

prevent

Implements least privilege to restrict access to WiFi credentials only to necessary users or processes, mitigating broad exposure within the UniFi Play network.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1552 Unsecured Credentials Credential Access

Adversaries may search compromised systems to find and obtain insecurely stored credentials.

attack.mitre.org →

Why these techniques?

Remote unauthenticated network access via improper access control directly enables exploitation of public-facing apps (T1190) and results in exposure of WiFi credentials (T1552).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

An Improper Access Control vulnerability could allow a malicious actor with access to the UniFi Play network to obtain UniFi Play WiFi credentials. Affected Products: UniFi Play PowerAmp (Version 1.0.35 and earlier) UniFi Play Audio Port (Version 1.0.24 and earlier)…

Mitigation: Update UniFi Play PowerAmp to Version 1.0.38 or later Update UniFi Play Audio Port to Version 1.1.9 or later

Deeper analysisAI

CVE-2026-22566 is an Improper Access Control vulnerability (CWE-284) in UniFi Play PowerAmp versions 1.0.35 and earlier, and UniFi Play Audio Port versions 1.0.24 and earlier. Published on 2026-04-13, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). The issue stems from inadequate access controls that expose sensitive information within the UniFi Play network environment.

A malicious actor with access to the UniFi Play network can exploit this vulnerability remotely over the network with low attack complexity, requiring no privileges, authentication, or user interaction. Exploitation allows the attacker to obtain UniFi Play WiFi credentials, leading to high-impact confidentiality loss without affecting integrity or availability.

Ubiquiti's security advisory recommends updating UniFi Play PowerAmp to version 1.0.38 or later and UniFi Play Audio Port to version 1.1.9 or later as the primary mitigation.
