What is CVE-2025-0651?

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. This may lead to deletion of crucial files owned by the System user, posing significant risks to system integrity and data availability. Affected versions include WARP prior to 2024.12.492.0.

Affected Version(s)

WARP Windows 0 < 2024.12.492.0

Exploit Proof of Concept (PoC)
