{"cve":"CVE-2025-66236","nvd":{"published":"2026-04-13T15:17:05.953","modified":"2026-10-07T09:10:00.160","status":"Analyzed","description":"Before Airflow 3.2.0, it was unclear that secure Airflow deployments require the Deployment Manager to take appropriate actions and pay attention to security details and security model of Airflow. Some assumptions the Deployment Manager could make were not clear or explicit enough, even though Airflow's intentions and security model of Airflow did not suggest different assumptions. The overall security model [1], workload isolation [2], and JWT authentication details [3] are now described in more detail. Users concerned with role isolation and following the Airflow security model of Airflow are advised to upgrade to Airflow 3.2, where several security improvements have been implemented. They should also read and follow the relevant documents to make sure that their deployment is secure enough. It also clarifies that the Deployment Manager is ultimately responsible for securing your Airflow deployment. This had also been communicated via Airflow 3.2.0 Blog announcement [4].\n\n[1] Security Model:  https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html \n[2] Workload isolation:  https://airflow.apache.org/docs/apache-airflow/stable/security/workload.html \n[3] JWT Token authentication:  https://airflow.apache.org/docs/apache-airflow/stable/security/jwt_token_authentication.html \n[4] Airflow 3.2.0 Blog announcement:  https://airflow.apache.org/blog/airflow-3.2.0/ \n\n\n\nUsers are recommended to upgrade to version 3.2.0, which fixes this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-532"],"references":["https://github.com/apache/airflow/pull/58662","https://lists.apache.org/thread/g8fyy1tkmxkkfk7tx2v6h8mvwzpyykbo","http://www.openwall.com/lists/oss-security/2026/04/13/6"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2025-66236","score":0.00439,"percentile":0.37833,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j86x-fwp2-qh7v","url":"https://osv.dev/vulnerability/GHSA-j86x-fwp2-qh7v","summary":"Apache Airflow: Secrets from Airflow config file logged in plain text in DAG run logs UI","modified":"2026-09-10T03:51:02.219006238Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.0.0 <3.2.0"],"fixed":["3.2.0"]}]},{"id":"PYSEC-2026-8","url":"https://osv.dev/vulnerability/PYSEC-2026-8","summary":"","modified":"2026-06-10T17:00:29.982257630Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.0.0 <3.2.0"],"fixed":["3.2.0"]}]}],"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).
