Unauthorized DAG clearing via inconsistent request identifiers
Published Oct 14, 2023 · Updated Feb 13, 2025
Improper access control in Apache Airflow before 2.7.2 allows remote authenticated users to clear DAGs outside their authorized scope. The web authorization decorator accepts a DAG ID from the first available route, query, form, or JSON parameter instead of rejecting inconsistent values, so authorization can cover one DAG while the request acts on another. An account with access to at least one DAG can submit conflicting DAG IDs and gain write access to resources for otherwise inaccessible DAGs, interrupting their scheduled work.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
