{"id":"BIT-airflow-2026-59244","summary":"Apache Airflow: Secrets masker: `var.json` Variable values not masked in the Rendered Templates UI","details":"Apache Airflow's secrets masker did not mask `var.json` Variable values whose value is a dict in the Rendered Templates UI — the dict value failed an `isinstance(str)` guard — so a secret stored as a JSON Variable and referenced in a template via `var.json` was displayed in cleartext to any user with access to that task's Rendered Templates view. Users are advised to upgrade to apache-airflow 3.3.1 or later, which masks nested Variable values regardless of type.","aliases":["CVE-2026-59244","PYSEC-2026-3706"],"modified":"2026-09-08T08:45:30.256967636Z","published":"2026-08-17T05:39:25.499Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/08/12/7"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/68975"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/fncod6vttfo5fvmfs3h9r8s2kmm9j1n6"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59244"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-59244.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
