CVE-2026-31846

Missing authentication in the /goform/ate endpoint in Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 allows an adjacent unauthenticated attacker to retrieve sensitive device information, including the administrator password. An attacker can decode this value to obtain valid administrative credentials and authenticate to the device.
