{"id":"CVE-2026-46764","aliases":["BIT-airflow-2026-46764","GHSA-qphr-3mvq-v466","PYSEC-2026-2354"],"url":"https://o3.security/vulnerability/CVE-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.","published":"2026-06-01T07:45:48.288Z","modified":"2026-08-12T03:51:13.774178788Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":{"score":0.00366,"percentile":0.29863,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow","fixedVersion":"3.2.2"}],"fix":{"url":"https://github.com/apache/airflow/pull/67112","label":"apache/airflow#67112"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/31/14"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46764.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/ctrbj7q3m86g4qxmo9ponojgmzrcoqpv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46764"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/67112"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.774178788Z"}}
