CVE-2026-9274

Secret extraction via UART-accessible runtime memory

Published May 25, 2026 · Updated May 25, 2026

Cleartext storage in CP PLUS EzyKam+ firmware 02.21.031 and earlier allows physically proximate attackers to extract secrets via UART. The camera leaves cryptographic private keys, Wi-Fi credentials, and configuration data unprotected in runtime RAM readable through the UART interface. Physical possession and UART access are required; extracted keys and credentials enable device impersonation, traffic decryption, and wireless-network access.
