CVE-2026-42204Public exploitNetwork attack vector

Authenticated host command execution via bare ampersands

Published Jul 6, 2026 · Updated Jul 6, 2026

OS command injection in coolLabs Coolify 4.0.0-beta.471 through 4.0.0-beta.473 allows remote authenticated users to execute host commands. ValidationPatterns.php permits bare ampersands in SHELL_SAFE_COMMAND_PATTERN, and ApplicationDeploymentJob.php interpolates the accepted command into bash -c without neutralizing the separator. Any team Member can reach the affected Docker Compose command fields; execution occurs in coolify-helper, whose mounted Docker socket permits root control of the Linux host.
