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.","epss":{"date":"2026-11-02","percentile":0.30415,"score":0.00366},"exploits":[],"kev":null,"metrics":[{"score":4.3,"severity":"medium","source":"ADP: CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"}],"modifiedAt":1793689037602,"publishedAt":1780299948288,"references":[{"source":"CNA: apache","tags":["patch"],"url":"https://github.com/apache/airflow/pull/67112"},{"source":"CNA: apache","tags":["vendor-advisory"],"url":"https://lists.apache.org/thread/ctrbj7q3m86g4qxmo9ponojgmzrcoqpv"},{"source":"ADP: CVE","tags":[],"url":"http://www.openwall.com/lists/oss-security/2026/05/31/14"}],"remediation":[{"kind":"fix","source":"CNA: apache","text":"The reporting source identifies this reference as a patch.
