CVE-2026-12815Public exploitNetwork attack vector

Authenticated command execution via unescaped image reference

Published Jun 21, 2026 · Updated Jun 21, 2026

OS command injection in Coolify 4.0.0 allows remote authenticated users to execute commands via a crafted Docker image reference. Deployment image parsing embeds the normalized reference, including shell metacharacters, into a docker pull command string without neutralization. Low-privileged access to control an image reference is required; successful exploitation runs commands with deployment worker or server privileges.
