CVE-2026-84694Network attack vectorHinoki check available

Authenticated host command execution via unescaped variable keys

Published Sep 2, 2026 · Updated Sep 2, 2026

OS command injection in coolLabs Coolify before 4.2.0 allows remote authenticated users to execute commands on managed server hosts. Coolify inserts unescaped environment-variable key names into Docker command strings sent through SSH, so shell metacharacters alter the host command. Any authenticated user allowed to manage an application's environment can reach the path and execute commands outside its container.
