Vulnerability AssessmentAI

Exploitation Requires local access to an Android device running Samsung Health prior to version 7.00.0.107, and the ability to execute code at low privilege level on that device (e.g., a sideloaded or malicious Play Store app). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 4.8 (Medium) accurately reflects the constrained risk profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A malicious third-party Android application installed on the victim's Samsung device - with only standard low-privilege permissions - queries Samsung Health's improperly protected data interface to enumerate paired Bluetooth wearables, such as Galaxy Watch device identifiers or pairing status. The attacker uses this information for device fingerprinting or to correlate the victim's health-related hardware. …
Remediation Update Samsung Health to version 7.00.0.107 or later, available via the Galaxy Store or Google Play Store on affected Samsung Android devices. … Detailed patch versions, workarounds, and compensating controls in full report.
