{"cve":"CVE-2026-46764","nvd":{"published":"2026-06-01T09:16:20.073","modified":"2026-07-21T19:10:00.107","status":"Modified","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-639"],"references":["https://github.com/apache/airflow/pull/67112","https://lists.apache.org/thread/ctrbj7q3m86g4qxmo9ponojgmzrcoqpv","http://www.openwall.com/lists/oss-security/2026/05/31/14"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-46764","score":0.00366,"percentile":0.3043,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qphr-3mvq-v466","url":"https://osv.dev/vulnerability/GHSA-qphr-3mvq-v466","summary":"Apache Airflow has an Authorization Bypass Through User-Controlled Key","modified":"2026-07-13T16:42:51.861384044Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.2"],"fixed":["3.2.2"]}]},{"id":"PYSEC-2026-2354","url":"https://osv.dev/vulnerability/PYSEC-2026-2354","summary":"Apache Airflow has an Authorization Bypass Through User-Controlled Key","modified":"2026-07-13T16:42:51.861384044Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.2"],"fixed":["3.2.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
