Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, Dokploy passes user-controlled values directly into shell commands via unquoted template literal interpolation in the registry credential testing and Docker Swarm cluster management endbpoints. Both endpoints have a safe local code path (using execFileAsync or the Docker API) but a vulnerable remote path (using execAsyncRemote which runs the shell string via SSH). This vulnerability is fixed in 0.29.13.
