What is CVE-2026-27955?

Coolify, an open-source tool designed for managing servers, applications, and databases, has a command injection vulnerability in its executeInDocker() helper. This occurs before version 4.0.0-beta.464, where user-controlled fields for custom build and start commands can manipulate command execution. Due to insufficient escaping of single quotes, an attacker can exploit this issue to execute arbitrary commands on the host server, outside the intended Docker container context. Upgrading to version 4.0.0-beta.464 or later mitigates this vulnerability.
