The BLE implementation of the COROS smartwatch does not support LE Secure Connections and instead enforces BLE Legacy Pairing. In BLE Legacy Pairing, the Short-Term Key (STK) can be easily guessed. This requires knowledge of the Temporary Key (TK), which, in the case of the COROS Pace 3, is set to 0 due to the Just Works pairing method. An attacker within Bluetooth range can therefore perform sniffing attacks, allowing eavesdropping on the communication.","severity":{"version":"3.1","score":6.8,"vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","level":"medium","assessor":"adp","from":"cve"},"epss":{"day":"2026-11-11","score":0.00399,"percentile":0.34592,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-306"],"published":"2025-06-20T00:00:00Z","modified":"2026-06-17T09:12:44Z","products":[{"vendor":"yftech","product":"coros_pace_3_firmware"}],"references":[{"url":"https://syss.de","tags":["Third Party Advisory"]},{"url":"https://support.coros.com/hc/en-us/articles/20087694119828-COROS-PACE-3-Release-Notes","tags":["Release Notes"]},{"url":"https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2025-023.txt","tags":["exploit","Exploit","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2025-32876"},{"url":"https://github.com/advisories/GHSA-rvp9-hfhr-8ggg"}],"sources":{"cve":[{"id":"CVE-2025-32876","description":"An issue was discovered on COROS PACE 3 devices through 3.0808.0.
