Description¶
Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, swarm.getNodes, swarm.getNodeInfo, swarm.getNodeApps, and swarm.getAppInfos in apps/dokploy/server/api/routers/swarm.ts accept another organization’s serverId without an activeOrganizationId ownership check, and getNodeInfo in packages/server/src/services/docker.ts interpolates nodeId into execAsyncRemote, allowing a caller with server:read permission to execute arbitrary commands as the configured SSH user on another tenant’s server. This issue is fixed in version 0.29.13.
