CVE-2024-43202Network attack vector

Remote code execution via unsafe YAML construction

Published Aug 20, 2024 · Updated Aug 20, 2024

Code injection in Apache DolphinScheduler 3.0.0 through 3.2.1 allows remote attackers to execute arbitrary code through crafted YAML. Kubernetes and loop-task parsers pass YAML to SnakeYAML constructors that resolve attacker-selected Java types instead of restricting construction to expected classes. Reachability requires a worker to parse a crafted Kubernetes or loop-task YAML definition, after which code runs with the worker service's privileges.
