AI risk analysis

Summary: The flaw allows any authenticated user with asset-read access to enumerate asset events for all Dags in the deployment, including those they are not authorized to see, due to missing access control filters.
Exploitability: Exploitation is relatively easy as long as an attacker has basic authentication and asset-read permissions. Precondition is the presence of per-Dag access control.
Blast radius: If exploited, it could reveal sensitive information about Dags not accessible to the user, potentially leading to unauthorized access or data exposure.
Prioritized remediation: Upgrade Apache Airflow to version 3.3.2 or later to apply necessary access control filters.

NVD description

Apache Airflow's `/assets/events` API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID, run ID and event timestamps — for Dags they have no permission to see. Because the filter was also absent from the count query, `total_entries` and pagination disclosed the existence of hidden Dags even without inspecting individual rows. Deployments are affected whenever per-Dag access control is used to separate teams or tenants; no special configuration is required. Upgrade to apache-airflow 3.3.2 or later.
