CVE-2025-11921Public exploit

Root command execution via unsanitized energymodes input

Published Nov 24, 2025 · Updated Nov 24, 2025

Command injection in Bjango iStat Menus 7.10.4 allows local users to execute arbitrary commands as root through its XPC daemon. The com.bjango.istatmenus.daemon processCommand:reply: method inserts user-controlled energymodes JSON values into a pmset command and passes the result to system() without validation. Any local process can connect because the XPC listener checks no code signature, entitlement, or bundle identifier, so an unprivileged account gains root execution.
