CVE-2026-72866 Dokploy CVE debrief

Who should care

Administrators and users of Dokploy should assess exposure and apply the patch in version 0.29.13. Affected operators, platforms, vulnerability-management, and security teams need to review and mitigate this high-severity authentication bypass vulnerability. Defenders should prioritize patching and restrict WebSocket handler access to prevent potential unauthorized access to interactive terminals.

Why it matters

CVE-2026-72866 is a high-severity authentication bypass vulnerability in Dokploy that allows authenticated users to access interactive terminals on the host without proper authorization. Defenders should prioritize patching to version 0.29.13 and restrict WebSocket handler access.

• Potential unauthorized access to interactive terminals
• Possible elevation of privileges without organization role or server-access checks
• Need for verification of affected versions and deployments
• Requirement for monitoring and restricting WebSocket handler access

Technical summary

The WebSocket handler in Dokploy validates a session but does not authorize access to the requested server. An authenticated user can connect to /terminal?serverId=local and obtain an interactive terminal on the Dokploy host without an organization role or server-access check. This allows potential unauthorized access to interactive terminals and possible elevation of privileges without organization role or server-access checks. The issue is fixed in version 0.29.13, which addresses the authorization bypass vulnerability.
