What is CVE-2026-72863?
CVE-2026-72863 is a critical missing authorization vulnerability in dokploy, published on 10 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
