CVE-2026-23902Network attack vector

Cross-tenant workflow execution via missing tenant validation

Published Apr 24, 2026 · Updated Apr 24, 2026

Incorrect authorization in Apache DolphinScheduler before 3.4.1 allows remote authenticated users to run workflows under nonexistent tenants. Workflow trigger and backfill paths accept a caller-supplied tenant code without confirming that TenantDao can resolve it, so execution proceeds under an undefined tenant context. System login access and permission to execute a workflow are required; the flaw crosses tenant authorization boundaries but does not enable unauthenticated access.
