CVE-2026-32324

MQTT traffic decryption via reusable embedded keys

Published Apr 17, 2026 · Updated Apr 17, 2026

Hard-coded cryptographic keys in all versions of Anviz CX7 Firmware allow local users to decrypt MQTT traffic and access messaging channels. The firmware image embeds reusable certificate and key material, so one recovered credential set applies beyond a single terminal. Access to the firmware image and MQTT traffic is required; the exposed material enables traffic decryption and unauthorized channel interaction but not a service interruption.
