CVE-2026-34153Network attack vector

Authenticated RCE via unescaped file-mount path

Published Jul 6, 2026 · Updated Jul 6, 2026

OS command injection in Coolify before 4.0.0-beta.471 allows remote authenticated users to execute commands through a file-mount path. The submitFileStorage flow stores an unvalidated path in fs_path, and LocalFileVolume::saveStorageOnServer interpolates it and parent_dir into shell commands before escaping. Permission to add file storage is required; saving the volume sends the commands over SSH to the Coolify host or a managed deployment server.
