Apache Airflow 3.2.2 Fix: EventLogs API ID Enumeration Priv Escalation
CVE-2026-46764 Published on June 1, 2026
Apache Airflow: Event Log detail endpoint bypasses DAG-scoped event log permission filter
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.
