Posted on 04 August 2023
The Canon PIXMA TR4550 stores sensitive data, such as the SSID and the Wi-Fi pre-shared key (PSK), unencrypted in its persistent storage (EEPROM). Resetting the product to factory settings does not securely delete this sensitive information. Versions 1.020 and 1.080 are affected.
