WebSocket Session Authorization Bypass in Dokploy

Publication date: 2026-08-10

Last updated on: 2026-08-10

Assigner: GitHub, Inc.

Description

Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, Dokploy's WebSocket handlers (in-app terminals and log streamers) authenticate the session but never authorize it. They establish who the user is via validateRequest() and then proceed without consulting the role/permission model that every tRPC procedure enforces. Any authenticated member, can therefore open an interactive shell into any container on the host, including the dokploy container that mounts the Docker socket, and from there obtain root on the host, escaping the application and crossing every tenant boundary. This vulnerability is fixed in 0.29.13.

Attack-Flow Graph

Executive Summary

Dokploy before version 0.29.13 has a WebSocket authentication flaw where sessions are authenticated but not authorized. This allows any authenticated user to access interactive shells in any container, including the Dokploy container with Docker socket access, leading to potential root access on the host and full tenant boundary breaches.

Detection Guidance

Check Dokploy version with 'dokploy --version'. If it is below 0.29.13, the system is vulnerable. Inspect running containers for unauthorized WebSocket connections or unexpected shell access using 'docker ps' and 'docker exec -it <container> sh'.

Impact Analysis

An attacker could gain root access to the host system, bypass all tenant isolation, and compromise all data and services running on the affected Dokploy instance. This includes accessing sensitive data, modifying configurations, or disrupting operations.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection and access control, such as GDPR's security principles or HIPAA's access controls. It enables unauthorized access to sensitive data, risking data breaches and non-compliance penalties.

Mitigation Strategies

Upgrade Dokploy to version 0.29.13 or later immediately. Ensure no unauthorized containers or shells are running. Review user permissions and disable unnecessary accounts.
