CVE-2026-50746 is a critical improper access control vulnerability in Ubiquiti UniFi Connect Application affecting version 3.4.16 and earlier. The flaw allows a malicious actor with network access to reach functionality in the application that can be abused to trigger command injection on the underlying host device. Available reporting indicates the issue is remotely exploitable over the network, requires no user interaction, and has been described as enabling unauthenticated exploitation by a network-adjacent attacker. Successful exploitation can result in attacker-controlled command execution in the context of the affected device, creating a direct path from insufficient access restrictions in the application to host-level compromise. The issue is fixed in UniFi Connect Application version 3.4.20.
