SCA: security update for github.com/fleetdm/fleet/v4 (GHSA-rphv-h674-5hp2)

high Tenable Self-Hosted Container Security Plugin ID 440058

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-27806)

Solution

Update the github.com/fleetdm/fleet/v4 library and its related packages to version 4.81.1 or later.
