CVE-2026-43917

What is known

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.

Business impact

Successful exploitation of CVE-2026-43917, a medium vulnerability (CVSS 5.3) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
