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.","publishedAt":"2025-06-20T00:00:00.000Z","updatedAt":"2025-06-24T15:27:06.224Z","severity":{"score":6.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","source":"CISA-ADP"},"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://syss.de","https://support.coros.com/hc/en-us/articles/20087694119828-COROS-PACE-3-Release-Notes","https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2025-023.txt"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:08:55.257Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/32xxx/CVE-2025-32876.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-32876","state":"PUBLISHED","datePublished":"2025-06-20T00:00:00.000Z","dateUpdated":"2025-06-24T15:27:06.224Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2025-04-11T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"An issue was discovered on COROS PACE 3 devices through 3.0808.0.
