Technical details

An incorrect authorization vulnerability (CWE-863) exists in the Apache DolphinScheduler API. The `/v2` experimental interface fails to implement necessary permission checks, allowing remote, unauthenticated attackers to interact with the API. By sending specially crafted network requests to this endpoint, an attacker can bypass security controls to access or modify data. The vulnerability is present in versions prior to 3.4.2 and is addressed in the 3.4.2 release.
