Description
sshportal through 1.19.5 contains a missing authorization vulnerability in the management shell 'key show' command that allows authenticated non-admin users to obtain decrypted backend private SSH keys. Attackers can request predictable key names like 'default' or 'host' to retrieve private keys and connect directly to backend hosts, bypassing ACLs and session recording.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-111638 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
