{"id":"BIT-airflow-2025-68438","summary":"Apache Airflow: Secrets in rendered templates could contain parts of sensitive values when truncated","details":"In Apache Airflow versions before 3.1.6, when rendered template fields in a Dag exceed [core] max_templated_field_length, sensitive values could be exposed in cleartext in the Rendered Templates UI. This occurred because serialization of those fields used a secrets masker instance that did not include user-registered mask_secret() patterns, so secrets were not reliably masked before truncation and display.\n\nUsers are recommended to upgrade to 3.1.6 or later, which fixes this issue","aliases":["CVE-2025-68438","GHSA-3qmm-r55x-hpxx","PYSEC-2026-9"],"modified":"2026-09-08T08:45:25.365382410Z","published":"2026-01-21T08:39:22.633Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:python:*:*"]},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/01/15/5"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/55n7b4nlsz3vo5n4h5lrj9bfsk8ctyff"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68438"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.1.0"},{"fixed":"3.1.6"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2025-68438.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
