CVE-2026-111638: sshportal 'key show' Command Missing Authorization

Sources read

Source agreement

0/2

Evidence confidence

%44

Short explanation

sshportal through versions 1.19.5 contains a missing authorization vulnerability in the management shell 'key show' command. This allows authenticated non-admin users to obtain decrypted backend private SSH keys.

Why does it matter?

Authenticated attackers can request predictable key names to retrieve private keys and connect directly to backend hosts, bypassing access control lists and session recording.

What should be done?

Follow vendor advisories as patch status is unverified in official sources
Review management shell access permissions and user roles
