CVE-2025-5199Public exploit

Root code execution via user-owned daemon binary

Published Jul 11, 2025 · Updated Jul 14, 2025

Incorrect default permissions in Canonical Multipass 1.15.1 and earlier on macOS allow local users to execute arbitrary code as root. The installer leaves the multipassd binary owned by the installing user although a LaunchDaemon executes that path with administrative privileges. Exploitation requires replacing that binary and waiting for a system restart, after which the payload performs arbitrary root actions.
