CVE-2026-66082: CWE-863 Incorrect Authorization in Apache Software Foundation Apache DolphinScheduler
Description
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.

Technical Analysis
Apache DolphinScheduler versions prior to 3.4.3 contain an authorization bypass vulnerability (CWE-863) where certain endpoints verify permissions against the supplied projectCode but do not confirm that the targeted resource belongs to that project. An authenticated user with permissions in one project can supply that project's code along with resource identifiers from other projects, bypassing access controls. Affected endpoints include POST /projects/{projectCode}/schedules/{id}/online and /offline to activate or deactivate workflow schedules, and POST /projects/{projectCode}/workflow-definition/{code}/release to change the online/offline state of workflow definitions. Successful exploitation enables unauthorized modification of workflow availability and task execution interference across projects.
Potential Impact
Exploitation allows authenticated users to bypass project-level access controls and perform unauthorized operations on workflow schedules and definitions in other projects. This can disrupt workflow availability and task execution in projects the user is not authorized to access, potentially impacting operational integrity and workflow management.
Mitigation Recommendations
Users should upgrade Apache DolphinScheduler to version 3.4.3 or later, where this authorization bypass vulnerability is fixed. No alternative mitigations are specified; applying the official patch is the recommended remediation.
