CVE-2026-43917
Dokploy: Cross-Organization IDOR - Multiple tRPC endpoints missing activeOrganizationId validation
Description
Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.19.0 and earlier, the protectedProcedure middleware only verifies the user is authenticated - it does NOT enforce organization scoping. Each endpoint must individually verify the resource's org matches the session's activeOrganizationId. This affects the following endpoints: allByType, killProcess, and removeDeployment in deployment.ts; delete in rollbacks.ts; create, one, update, remove, manualBackupPostgres, MySql, Mariadb, Mongo, Compose, WebServer, and listBackupFiles in backup.ts; list, one, delete, update, runManually, and restoreVolumeBackupWithLogs in volume-backups.ts; getNodes, removeWorker, addWorker, and addManager in cluster.ts; and create in mount.ts.
