AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Local PR:L access required; scope changes because DiagTrack runs at elevated privilege and discloses data outside the attacker's security domain; pure confidentiality impact.

Insufficient granularity of access control in Windows Connected User Experiences and Telemetry allows an authorized attacker to disclose information locally.
AnalysisAI
Local information disclosure in the Windows Connected User Experiences and Telemetry (DiagTrack) service allows a low-privileged authenticated local attacker to read sensitive data outside their authorized security scope. The CVSS scope-change metric (S:C) indicates the exposed data originates from a security domain beyond the telemetry component itself - likely higher-privileged OS subsystem data. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing low-privileged authenticated local session on the target Windows system (PR:L, AV:L) - the attacker must already have code execution or interactive logon access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.5 with vector AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N reflects a realistic but bounded threat: exploitation requires an existing low-privileged local foothold, meaningfully reducing real-world attack surface compared to remote or unauthenticated vulnerabilities. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Microsoft security update for the specific Windows build in use, available via Windows Update, WSUS, or Microsoft Update Catalog. … Detailed patch versions, workarounds, and compensating controls in full report. |
