CVE-2026-78214 · Severity: medium · CVSS 5.3 · Published 2026-09-29

Apache DolphinScheduler is a workflow orchestration platform that manages scheduled tasks and operational processes. An authentication bypass vulnerability allows remote attackers to access restricted Actuator management endpoints by sending specially crafted percent-encoded requests, bypassing security checks. Successful exploitation may expose operational and configuration information, and potentially grant access to sensitive management functions depending on application configuration.

Technologies: [Apache DolphinScheduler](https://junglewise.ai/threats/technologies/apache-dolphinscheduler-1). Vendors: [Apache](https://junglewise.ai/threats/vendors/apache).

## Technical details

The vulnerability exists in path matching logic for Actuator endpoint protection, where the application fails to properly handle percent-encoded paths in security checks. An unauthenticated remote attacker can craft requests with encoded path traversal sequences that bypass authentication validation. The vulnerability affects DolphinScheduler before version 3.4.3 and is fixed in 3.4.3.
