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

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match
prevent

Directly requires implementation of input validation mechanisms to prevent command injection from improper input handling in the affected UniFi Play devices.

SI-2 Flaw Remediation good match
prevent

Mandates timely identification, reporting, and correction of flaws like this improper input validation vulnerability through patching to versions 1.0.38+ and 1.1.9+.

RA-5 Vulnerability Monitoring and Scanning partial match
detect

Enables vulnerability scanning to identify improper input validation flaws enabling command injection prior to exploitation.

Security SummaryAI

CVE-2026-22563 consists of a series of improper input validation vulnerabilities (CWE-20) that could enable command injection attacks. The affected products are UniFi Play PowerAmp in versions 1.0.35 and earlier, and UniFi Play Audio Port in versions 1.0.24 and earlier.

With a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), the vulnerability is exploitable remotely over the network with low attack complexity, requiring no privileges, user interaction, or special conditions. A malicious actor with access to the UniFi Play network can leverage these flaws to inject and execute arbitrary commands on the affected devices.

The 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. Additional details are available in the Ubiquiti UniFi community release at https://community.ui.com/releases/Security-Advisory-Bulletin-063/e468dd4b-5090-4ef8-89d8-939903c08e83.

T1210 Exploitation of Remote Services Lateral Movement
Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.
attack.mitre.org →
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
attack.mitre.org →
Why these techniques?

Remote unauthenticated command injection vulnerability enables exploitation of public-facing or remote services (T1190, T1210) and facilitates arbitrary command execution via Unix Shell (T1059.004) on Linux-based UniFi devices.
