Updated Sep 29, 2026
Apache
Parameter Value
CVSS 4.3 (MEDIUM)
Affected Versions before 3.4.3.
Fixed In 3.4.3
Type CWE-863 (Incorrect Authorization)
Vendor Apache
Public PoC No

An incorrect authorization check in Apache DolphinScheduler allows an authenticated user with only read permission for a project to modify a workflow instance in that project through the PUT /projects/{projectCode}/workflow-instances/{id} endpoint. The endpoint does not enforce the write permission required for this operation, allowing the user to make unauthorized changes to workflow instances. This issue affects Apache DolphinScheduler: before 3.4.3.

Users are recommended to upgrade to version 3.4.3, which fixes the issue.
