CVE-2025-34161 — Coolify versions prior to v4.0.0-beta.420.7 are vulnerable to a remote code execution vulnerability in the project deployment workflow

Critical CVSS 9.4

Coolify versions prior to v4.0.0-beta.420.7 are vulnerable to a remote code execution vulnerability in the project deployment workflow. The platform allows authenticated users, with low-level member privileges, to inject arbitrary shell commands via the Git Repository field during project creation. By submitting a crafted repository string containing command injection syntax, an attacker can execute arbitrary commands on the underlying host system, resulting in full server compromise.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
