Because HITL prompts and TaskInstance fields routinely carry operator parameters and free-form context attached to a task, the leak widens visibility of DAG-run data beyond the intended per-DAG RBAC boundary for every authenticated user.\n\nUsers are recommended to upgrade to version 3.2.1 , which fixes this issue.","epss":{"date":"2026-11-02","percentile":0.28864,"score":0.00352},"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":1793688883499,"publishedAt":1777034200202,"references":[{"source":"CNA: apache","tags":["patch"],"url":"https://github.com/apache/airflow/pull/64822"},{"source":"CNA: apache","tags":["vendor-advisory"],"url":"https://lists.apache.org/thread/sk2wj0x48o8qb4p7c47gvnhjbm0mg396"},{"source":"ADP: CVE","tags":[],"url":"http://www.openwall.com/lists/oss-security/2026/04/24/3"}],"remediation":[{"kind":"fix","source":"CNA: apache","text":"The reporting source identifies this reference as a patch.
