CVE-2026-33000 is an improper input validation vulnerability in Ubiquiti UniFi OS devices that allows command injection by a network-accessible attacker with high privileges. Available reporting indicates this issue is the authenticated variant of the same command-injection sink later exposed without authentication as CVE-2026-34910. Bishop Fox described the vulnerable code path as a package-update handler that interpolated an attacker-controlled package name into a command string of the form sudo /usr/bin/uos runnable latest-versions %v and executed it via a sh -c shell wrapper without sufficient sanitization. In the authenticated case, the attacker must possess a valid high-privilege session or token, including a valid view:identity:update token, to reach the sink. Successful exploitation results in execution of attacker-supplied shell metacharacters and commands on the target UniFi OS device.
