Dokploy Certificate Path Traversal leads to Remote Code Execution

CVE advisorySeverity: CRITICAL (CVSS 9.9)

CVE-2026-72880

Dokploy is a self-hostable Platform as a Service (PaaS) designed for managing applications and deployments. As a PaaS management platform, it is commonly deployed as an internet-facing web-based interface or API to facilitate remote management and deployment operations, making its administrative and functional endpoints commonly reachable from the internet in typical deployments.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in Dokploy, a self-hostable Platform as a Service, that could allow an authenticated user to write or delete files outside of intended directories. This could potentially impact the integrity and availability of services managed by Dokploy.

  • Allows file system compromise by authenticated users.
  • Impacts platforms managing application deployments.
  • Confirm relevance and exposure of deployed Dokploy instances.

Attack Path

How an attacker could exploit the issue

An attacker with the ability to create or delete certificates can exploit this vulnerability by providing a specially crafted `certificatePath`. This path allows the attacker to write custom certificate content outside the designated directory or to delete files in unrelated directories. The vulnerability lies in how the `certificatePath` input is handled, leading to a bypass of intended directory restrictions.

  • Authenticated user required.
  • Path traversal with certificate operations.
  • Arbitrary file write and deletion.

Live Threat

Current exploitation, exposure, and threat context

An authenticated user with specific permissions in Dokploy could manipulate the `certificatePath` to write arbitrary content to files outside of the intended directory or delete directories. This could affect the integrity and availability of the Dokploy service and potentially the underlying system when supported by the advisory.

  • Service configuration files could be overwritten.
  • Arbitrary file writes or deletions are possible.
  • Service disruption or unauthorized file modification.

Operational Fix

Recommended remediation, mitigation, and detection steps

Application owners and infrastructure teams are likely responsible for addressing this vulnerability in Dokploy, as it impacts a self-hostable PaaS used for managing deployments. The first practical step is to identify all Dokploy instances, determine their reachability and business criticality, and then confirm the accountable owner to plan remediation activities based on risk.

  • Application and infrastructure teams own this.
  • Verify Dokploy instance reachability and criticality.
  • Plan remediation based on identified risk.

Frequently asked questions

What is Dokploy and how is it typically used?

Dokploy is a self-hosted Platform as a Service (PaaS) designed to simplify application deployment and management. Users run it on their own infrastructure to manage their software projects through a centralized web-based interface or API, effectively acting as an orchestration layer for their cloud or server resources.

What kind of security weakness is CVE-2026-72880?

This vulnerability is classified as Improper Neutralization of Special Elements used in an OS Command, known as CWE-78. In plain English, the software fails to properly sanitize user input when handling file paths for certificates. This allows an attacker to 'escape' the directory where certificates are supposed to be kept and interact with files elsewhere on the server's filesystem.

How can an attacker trigger this vulnerability?

An attacker needs an account with permission to create or delete certificates within Dokploy. By providing a specially crafted file path, they can trick the system into reading or writing files outside of the authorized directory. Simply having an account without these specific administrative-style certificate permissions is not enough to trigger the flaw.

Is my Dokploy instance at risk?

According to Halo Surface Signal, Dokploy is frequently deployed as an internet-facing service to allow remote management of applications. Because it often exposes administrative endpoints to the network, instances accessible over the internet are at higher risk of exploitation by an authenticated user compared to those restricted to internal, private networks.

How do I secure my Dokploy installation?

The primary response is to update your Dokploy installation to version 0.29.13 or newer, where this issue has been resolved. Before updating, identify all Dokploy instances running in your environment, determine which are accessible to potential attackers, and ensure that access controls are strictly managed for any users with certificate-related permissions.
