{"id":"BIT-airflow-2026-46764","summary":"Apache Airflow: Event Log detail endpoint bypasses DAG-scoped event log permission filter","details":"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.","aliases":["CVE-2026-46764","GHSA-qphr-3mvq-v466","PYSEC-2026-2354"],"modified":"2026-09-08T08:45:27.887912778Z","published":"2026-06-05T05:40:48.371Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/05/31/14"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/67112"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/ctrbj7q3m86g4qxmo9ponojgmzrcoqpv"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46764"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-46764.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.9.0"}
