Overview
Affected versions of this package are vulnerable to Cleartext Transmission of Sensitive Information in the process that handles SSID allowlist checks for internal network connections. An attacker can intercept sensitive information, such as access tokens and sensor data, by connecting the device to an untrusted or insecure Wi-Fi network, causing the app to fallback to the internal URL and transmit data over potentially unsafe channels.
