CVE-2026-66082: Apache DolphinScheduler: Cross-project authorization bypasses in DolphinScheduler API (schedule / workflow)
Noroxi assessment
Priority: Monitor (action score 26/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.30% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Apache Software Foundation Apache DolphinScheduler 3.4.3.
Low priority for now. Upgrade to Apache Software Foundation Apache DolphinScheduler 3.4.3 or later.

An authorization bypass vulnerability in Apache DolphinScheduler allows authenticated users to perform unauthorized operations on workflow schedules, workflow definitions, and task instances in other projects. The affected endpoints check permissions against the supplied projectCode but fail to verify that the target resource belongs to that project. An authenticated user with the required permissions in one project can supply that project's code together with a resource identifier from another project, bypassing the target project's access restrictions. The affected endpoints include: * POST /projects/{projectCode}/schedules/{id}/online and /offline: Activate or deactivate workflow schedules in another project. * POST /projects/{projectCode}/workflow-definition/{code}/release: Change the ONLINE/OFFLINE state of workflow definitions in another project. Successful exploitation allows users to alter workflow availability and interfere with task execution in projects they are not authorized to access. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.
