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.","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-1220"],"references":["https://github.com/apache/airflow/pull/64822","https://lists.apache.org/thread/sk2wj0x48o8qb4p7c47gvnhjbm0mg396","http://www.openwall.com/lists/oss-security/2026/04/24/3"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-38743","score":0.00352,"percentile":0.28618,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-p3v3-229h-mc63","url":"https://osv.dev/vulnerability/GHSA-p3v3-229h-mc63","summary":"Apache Airflow's authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance record","modified":"2026-07-13T16:42:35.825694840Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.1rc1"],"fixed":["3.2.1rc1"]}]},{"id":"PYSEC-2026-2351","url":"https://osv.dev/vulnerability/PYSEC-2026-2351","summary":"Apache Airflow's authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance record","modified":"2026-07-13T16:42:35.825694840Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.2.1rc1"],"fixed":["3.2.1rc1"]}]}],"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).
