Root command execution via unauthenticated privileged XPC helper
Published Aug 1, 2025 · Updated Aug 1, 2025
OS command injection in Alin Lupascu Pearcleaner 4.4.0 through 4.5.1 allows local users to execute arbitrary commands as root. The listener(_:shouldAcceptNewConnection:) handler accepts every XPC client without validating its identity, and runCommand passes the supplied string to /bin/bash -c. Exploitation requires local code execution and an installed helper that an administrator has already approved and activated as a root LaunchDaemon.
