CVE-2025-53825 in dokploy
Summary
by MITRE • 07/15/2025
Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to version 0.24.3, an unauthenticated preview deployment vulnerability in Dokploy allows any user to execute arbitrary code and access sensitive environment variables by simply opening a pull request on a public repository. This exposes secrets and potentially enables remote code execution, putting all public Dokploy users using these preview deployments at risk. Version 0.24.3 contains a fix for the issue.

The vulnerability identified as CVE-2025-53825 affects Dokploy, a self-hostable Platform as a Service solution that enables users to deploy applications without requiring extensive infrastructure management. This security flaw represents a critical oversight in the preview deployment functionality that undermines the fundamental security assumptions of the platform. The vulnerability specifically targets the unauthenticated access controls that should normally prevent unauthorized execution of code within the deployment environment.
The technical implementation of this vulnerability stems from insufficient authentication mechanisms within Dokploy's preview deployment system. When users create pull requests on public repositories, the system automatically initiates preview deployments without requiring proper authentication verification. This design flaw allows any external actor to trigger the deployment process and subsequently execute arbitrary code within the preview environment. The vulnerability manifests as a direct consequence of inadequate input validation and access control enforcement, creating a pathway for privilege escalation and unauthorized code execution.
The operational impact of this vulnerability extends beyond simple code execution capabilities, as it provides attackers with access to sensitive environment variables and system resources. The exposure of environment variables represents a particularly concerning aspect since these typically contain database credentials, API keys, and other confidential information that could be exploited for further attacks. The vulnerability affects all public Dokploy users who utilize preview deployments, creating a widespread security risk across the user base. The attack vector is particularly dangerous because it requires minimal effort from attackers, who only need to open a pull request to trigger the exploit.
From a cybersecurity perspective, this vulnerability aligns with CWE-287, which addresses improper authentication issues in software systems. The flaw demonstrates poor access control implementation and highlights the importance of proper authentication mechanisms in deployment environments. The vulnerability also maps to ATT&CK technique T1059, which covers command and script injection, as attackers can execute arbitrary commands within the preview deployment environment. Organizations using Dokploy must consider this vulnerability as part of their broader security posture assessment, particularly when dealing with public repositories that may be targeted by malicious actors.
The remediation for this vulnerability required implementing proper authentication checks before initiating preview deployments. Version 0.24.3 of Dokploy addresses this issue by enforcing authentication requirements for all deployment operations, ensuring that only authorized users can trigger preview deployments. This fix aligns with security best practices for deployment systems and demonstrates the importance of proper access control implementation. Organizations should immediately upgrade to version 0.24.3 or later to protect their deployments from potential exploitation. The vulnerability serves as a reminder of the critical importance of validating all user inputs and enforcing proper authentication mechanisms, especially in systems that handle sensitive data and deployment operations.
