CVE-2026-27806

Popis

Fleet is open source device management software. Prior to 4.81.1, 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. This vulnerability is fixed in 4.81.1.
