Low risk41th percentile — higher than 41% of all known CVEs
Summary
In Coolify prior to 4.0.0-beta.470, a critical authenticated remote code execution (RCE) vulnerability was found. The flaw is in the handling of the install_command parameter, which is directly concatenated into a shell command during Nixpacks build, allowing arbitrary command execution on the host.
Risk Assessment
An attacker can gain full control of the Coolify server with host-level privileges, leading to data theft, malware installation, or further compromise of the infrastructure.
Recommendation
Upgrade Coolify to version 4.0.0-beta.470 or later immediately. Restrict administrative access to trusted users only.
Original NVD description (English source)
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.
