CVE-2026-34034Public exploitNetwork attack vector

Host command execution via Sentinel token interpolation

Published Jul 7, 2026 · Updated Jul 7, 2026

OS command injection in coolLabs Coolify before 4.0.0-beta.466 allows remote authenticated users to execute commands on the host. The StartSentinel action and HasMetrics trait interpolate sentinel_token into Docker environment arguments and a shell-based curl command without restricting shell metacharacters. Access to server Sentinel settings is required, and saving a crafted token automatically restarts Sentinel and runs the injected command with host-level impact.
