CVE-2018-10626 Medtronic CVE debrief

CVE-2018-10626 is a medium-severity vulnerability affecting Medtronic MyCareLink Patient Monitor firmware. The update service fails to sufficiently verify the authenticity of uploaded data, allowing an attacker with per-product credentials and paired implantable cardiac device information to potentially upload invalid data to the Medtronic CareLink network. The vulnerability was published on August 10, 2018, and most recently modified on May 19, 2026. The CVSS 3.1 vector (AV:A/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N) indicates this requires adjacent network access, high attack complexity, and low privileges, with scope change and low impacts to confidentiality and integrity. The weakness is categorized as CWE-345 (Insufficient Verification of Data Authenticity). Affected products include MyCareLink 24950 and 24952 Patient Monitor firmware.
