## Summary The Orbit agent's FileVault disk encryption key rotation flow on collects a local user's password via a GUI dialog and interpolates it directly into a Tcl/expect script executed via `exec.Command("expect", "-c", script)`. Because the password is inserted into Tcl brace-quoted `send {%s}`, a password containing `}` terminates the literal and injects arbitrary Tcl commands. Since Orbit runs as root, this allows a local unprivileged user to escalate to root privileges. ## CWE - **CWE-78**: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') - **CWE-94**: Improper Control of Generation of Code ('Code Injection') ## Impact - Local privilege escalation to root: Any unprivileged local user on a managed endpoint can execute arbitrary commands as root ## Credit This vulnerability was discovered and reported by [bugbunny.ai](https://bugbunny.ai).
Update github.com/fleetdm/fleet/v4 to 4.81.1 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in go. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
