Summary

A security vulnerability in Cloudflare WARP for Windows enables users with limited privileges to create symbolic links in the C:\ProgramData\Cloudflare\warp-diag-partials directory. When the 'Reset all settings' option is triggered, the WARP service—operating with System privileges—can inadvertently delete files referenced by these symlinks.
