CVE-2020-1590
Status: ModifiedHigh (7.8)—
<p>An elevation of privilege vulnerability exists when the Connected User Experiences and Telemetry Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges on the victim system.</p> <p>To exploit the vulnerability, an attacker would first have to gain execution on the victim system, then run a specially crafted application.</p> <p>The security update addresses the vulnerability by correcting how the Connected User Experiences and Telemetry Service handles file operations.</p>
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Base score: 7.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.84%
- Percentile among all scored CVEs: 57
- Score date: 10/16/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
