Dokploy PaaS: Critical OS Command Injection CVE-2026-27130
A critical OS command injection vulnerability, CVE-2026-27130, has been identified in Dokploy, a self-hostable Platform as a Service (PaaS). The National Vulnerability Database (NVD) reports that Dokploy versions 0.26.6 and below are affected. This flaw, rated 9.9 CVSS (CRITICAL), stems from a chain of issues: inadequate input sanitization, a lack of schema validation, and direct shell interpolation.
The core problem lies in how Dokploy handles the appName parameter. User-controlled application names, passed through a cleanAppName function that only replaces spaces and converts to lowercase, are directly interpolated into shell commands. These commands are executed via execAsync() and execAsyncRemote(). An authenticated attacker can inject shell metacharacters (e.g., ;, $(, backticks, |, &) into the appName field during application creation. These malicious commands are then executed with server-level privileges whenever service operations (start, stop, remove, scale) are triggered.
This vulnerability, classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command), gives an authenticated attacker complete control over the underlying server. Dokploy has addressed this issue in version 0.26.7. Defenders running Dokploy must prioritize patching immediately.
What This Means For You
- If your organization uses Dokploy, you are running a critical risk. An authenticated attacker can achieve full remote code execution on your server. Check your Dokploy version immediately and ensure you are running 0.26.7 or higher. If you're on an affected version, patch now and audit logs for any unusual application creation or service operations from authenticated users.
