Published Aug 10, 2026

Updated

Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, the local branch of /docker-container-terminal in apps/dokploy/server/wss/docker-container-terminal.ts authenticates with validateRequest but does not authorize the attacker-controlled containerId against the caller's role, organization, or service access before passing it to docker exec, allowing any authenticated member to obtain a root shell in arbitrary containers on a self-hosted instance. This issue is fixed in version 0.29.13.
