CVE-2025-13733Public exploitHinoki check available

Root code execution via unauthenticated XPC helper

Published Dec 12, 2025 · Updated Dec 12, 2025

Privilege escalation in Dr.Buho BuhoNTFS 1.3.2 allows local users to execute arbitrary code as root through an unauthenticated XPC service. The privileged com.drbuho.disktool.NTFSHelperTool accepts every local XPC connection because its listener and connection validator approve clients without authentication, then setFSExecPath stores an attacker-chosen executable path. Any unprivileged local account can supply a binary path and trigger the mount method to run it as root, granting complete control of the Mac.
