Apache AirflowGHSA-qphr-3mvq-v466
Apache Airflow has an Authorization Bypass Through User-Controlled Key
Medium4.3CVE-2026-46764 · Published Jun 1, 2026 · updated Jul 13, 2026
The Event Log detail endpoint `GET /api/v2/eventLogs/{event_log_id}` in Apache Airflow fetched audit-log rows directly by numeric ID after only the generic Audit Log permission check, while the collection endpoint `GET /api/v2/eventLogs` applied per-Dag scoping. An authenticated UI/API user with audit-log read permission for one Dag could retrieve audit-log entries for any other Dag by guessing or enumerating the numeric event log ID. Affects deployments that rely on per-Dag audit-log scoping. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.
