Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, the buildRemoteDocker() function in packages/server/src/utils/providers/docker.ts interpolates the application-controlled dockerImage value directly into a docker pull shell command. An authenticated user with project access can set a crafted dockerImage through application.update and trigger application.deploy, causing execAsync() to execute arbitrary operating-system commands as the Dokploy server process. This issue is fixed in version 0.29.13.
