Official description

Improper Privilege Management vulnerability in Cloudflare WARP on Windows allows File Manipulation. User with a low system privileges  can create a set of symlinks inside the C:\ProgramData\Cloudflare\warp-diag-partials folder. After triggering the 'Reset all settings" option the WARP service will delete the files that the symlink was pointing to.
