CVE-2026-72737: Dokploy: Cross-organization IDOR in Dokploy backup destinations exposes another tenant's S3 credentials and backups

Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.29.8 and earlier, backup.create, backup.update, and backup.restoreBackupWithLogs in apps/dokploy/server/api/routers/backup.ts accept a client-controlled destinationId and use the referenced destination without verifying that destination.organizationId equals ctx.session.activeOrganizationId. An authenticated member with backup permissions for a service in one organization can cause another organization's S3 accessKey and secretAccessKey to be materialized by packages/server/src/utils/backups/utils.ts getS3Credentials on the attacker's service host, read that organization's backup objects, or redirect and poison backups across tenant boundaries.
