DescriptionAffected Tapo device firmware stores device-specific cryptographic material in plaintext within nonvolatile storage. An attacker with physical access to an affected device can recover this sensitive material from the firmware.  Successful exploitation of this vulnerability may result in the disclosure of device-specific cryptographic material and could, under certain conditions, increase the risk of unauthorized access to related protected information or communications.
