CVE-2025-32875Public exploit

Sensitive-data interception via unenforced BLE bonding

Published Jun 20, 2025 · Updated Jun 23, 2025

Cleartext BLE transmission in the COROS Android application 3.8.12 and earlier allows attackers to intercept sensitive data over Bluetooth. The application and watch neither initiate nor enforce pairing and bonding, so BLE traffic remains unencrypted even after manual Android bonding. Bluetooth-range access while the watch communicates is required; passive sniffing exposes API tokens, while an active middle device can force plaintext fallback.
