CVE-2026-34597: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in coollabsio coolify
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.

Technical Summary
CVE-2026-34597 is an OS command injection vulnerability in Coolify, an open-source server and application management tool. The flaw exists in the Nixpacks build pack handling of user-defined build parameters. The install_command parameter is concatenated unsafely into a shell command executed on the deployment host, enabling authenticated users to execute arbitrary commands with host-level privileges. This vulnerability is resolved in Coolify version 4.0.0-beta.470.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary commands on the deployment host with host-level privileges, leading to full compromise of the affected system. This can result in complete confidentiality, integrity, and availability loss of the host and its managed resources.
Mitigation Recommendations
Upgrade to Coolify version 4.0.0-beta.470 or later, where this vulnerability is fixed. Since this is an authenticated remote code execution issue, restricting access to trusted users and applying the official patch is critical. Patch status is confirmed fixed in 4.0.0-beta.470.
