CVE-2026-27130

Description

Dokploy is a free, self-hostable Platform as a Service (PaaS). Versions 0.26.6 and below have OS command injection through the appName parameter. 3 chained issues cause this problem: inadequate input sanitization, lack of schema validation and direct shell interpolation. User-controlled application names are passed through inadequate sanitization (cleanAppName function only replaces spaces and converts to lowercase) before being interpolated directly into shell commands executed via execAsync() and execAsyncRemote(). An authenticated attacker can inject shell metacharacters (e.g., ;, $(), backticks, |, &) in the appName field during application creation, which are then executed with server-level privileges when service operations (start, stop, remove, scale) are triggered. This issue has been resolved in version 0.26.7.

Techniques & Countermeasures

• CWE-78•Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

  The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
