Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID, run ID and event timestamps — for Dags they have no permission to see. Because the filter was also absent from the count query, `total_entries` and pagination disclosed the existence of hidden Dags even without inspecting individual rows. Deployments are affected whenever per-Dag access control is used to separate teams or tenants; no special configuration is required. Upgrade to apache-airflow 3.3.2 or later.","epss":{"date":"2026-11-02","percentile":0.50501,"score":0.00636},"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":1793689241233,"publishedAt":1790001167818,"references":[{"source":"CNA: apache","tags":["patch"],"url":"https://github.com/apache/airflow/pull/71741"},{"source":"CNA: apache","tags":["vendor-advisory"],"url":"https://lists.apache.org/thread/rx5lg86l0qkjl2s7dtmpqxjq0xplr4fy"},{"source":"ADP: CVE","tags":[],"url":"http://www.openwall.com/lists/oss-security/2026/09/21/3"}],"remediation":[{"kind":"fix","source":"CNA: apache","text":"The reporting source identifies this reference as a patch.
