Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

`cloudflared` versions prior to 2020.8.1 contain a local privilege escalation vulnerability on Windows systems. When run on a Windows system, `cloudflared` searches for configuration files which could be abused by a malicious entity to execute commands as a privileged user. Version 2020.8.1 fixes this issue.
