Deeper analysis
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.
