CVE-2026-42148Public exploit

Authenticated command execution via unescaped helper version

Published Jul 6, 2026 · Updated Jul 6, 2026

OS command injection in Coolify before 4.0.0-beta.474 allows local users to execute arbitrary commands through the helper image builder. The buildHelperImage method interpolates the dev_helper_version setting into a Docker build command without escaping shell metacharacters. Exploitation requires a development-mode instance, permission to change the setting, and a separate action that triggers the build; injected commands run on the server.
