CVE-2026-34597 Details
Description
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.470, a critical Authenticated Host Remote Code Execution (RCE) vulnerability was discovered in Coolify. The flaw resides in the handling of user-defined build parameters for the Nixpacks build pack. Specifically, the install_command provided by a user is directly concatenated into a shell command string that is executed on the deployment host during the building phase. An attacker can leverage this to escape the intended build context and execute arbitrary commands with host-level privileges. This vulnerability is fixed in 4.0.0-beta.470.
A critical authenticated remote code execution vulnerability has been identified in Coolify versions prior to 4.0.0-beta.470. The issue arises in the Nixpacks build pack, where user-defined install commands are directly concatenated into a shell command without proper sanitization. This allows attackers to escape the intended context and execute arbitrary commands on the host with elevated privileges.
Users are advised to update to Coolify version 4.0.0-beta.470 or later, where this vulnerability has been patched.
