CVE-2026-46764
Full vulnerability record from the local CVENow database.
Description
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.

"value": "El endpoint de detalle del registro de eventos 'GET /api/v2/eventLogs/{event_log_id}' en Apache Airflow recuperaba filas de registro de auditoría directamente por ID numérico después de solo la verificación genérica de permisos de registro de auditoría, mientras que el endpoint de colección 'GET /api/v2/eventLogs' aplicaba un alcance por Dag. Un usuario autenticado de UI/API con permiso de lectura de registro de auditoría para un Dag podía recuperar entradas de registro de auditoría para cualquier otro Dag adivinando o enumerando el ID numérico del registro de eventos. Afecta a las implementaciones que dependen del alcance por Dag del registro de auditoría. Se aconseja a los usuarios actualizar a 'apache-airflow' 3.2.2 o posterior."
