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.

Who should care
Healthcare organizations using Medtronic MyCareLink Patient Monitors, cardiac device security teams, medical device risk managers, and healthcare network security administrators responsible for protecting patient monitoring infrastructure.
Technical summary
The MyCareLink Patient Monitor's update service lacks sufficient verification of data authenticity during upload operations. An attacker possessing valid per-product credentials and information about a paired implantable cardiac device can exploit this weakness to submit invalid data to the Medtronic CareLink network. The attack requires adjacent network access and high complexity, with successful exploitation potentially affecting data integrity and confidentiality within the cardiac device monitoring ecosystem.
