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.
Security readout for executives and security teams
Plain-English summary
Dokploy 0.29.8 and earlier has a tenant-isolation flaw in backup destination handling. A logged-in user with backup permissions in one organization may access another organization’s S3 backup credentials and backup data, or interfere with backups across organizations. This is most urgent for multi-tenant Dokploy deployments.
Executive priority
Treat as urgent for any shared or multi-organization Dokploy environment. The business risk is exposure of cloud storage credentials and backups between tenants. Single-organization deployments may have lower practical impact but should still validate version and vendor guidance.
Technical view
The backup.create, backup.update, and backup.restoreBackupWithLogs paths accept a client-controlled destinationId without confirming destination.organizationId matches ctx.session.activeOrganizationId. This is an IDOR/missing authorization issue mapped to CWE-639 and CWE-862, with CVSS 9.6. The flaw can expose S3 accessKey and secretAccessKey via getS3Credentials and enable cross-tenant backup access or poisoning.
Likely exposure
Exposed systems are Dokploy deployments running version 0.29.8 or earlier, especially where multiple organizations or tenants use backup destinations. Exploitation requires an authenticated member with backup permissions for a service in one organization.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. The attack is low complexity after authentication and can cross tenant boundaries, affecting confidentiality and integrity of S3-backed backups.
Researcher notes
The key authorization gap is destinationId trust across backup router methods. Evidence identifies affected versions and vulnerable code paths, but the provided sources do not include exploit-in-the-wild confirmation or a named fixed release.
Mitigation direction
Identify all Dokploy instances and confirm whether they run 0.29.8 or earlier.
Review Dokploy’s GitHub advisory and vendor guidance for fixed versions or official workarounds.
Restrict backup permissions to trusted users until remediation is applied.
Audit backup destinations and S3 credentials for unexpected cross-organization use.
Rotate S3 credentials if cross-tenant exposure is suspected.
Validation and detection
Inventory Dokploy version across production, staging, and shared environments.
Check whether Dokploy is configured with multiple organizations or tenants.
Review users with backup permissions in each organization.
Inspect logs for unusual backup create, update, or restore activity involving backup destinations.
Verify vendor remediation has been applied once official guidance is available.
