{"id":"BIT-airflow-2026-75158","summary":"Apache Airflow: Assets events API returns asset events for every Dag with no per-Dag authorization filter","details":"Apache Airflow's `/assets/events` API returned asset events for every Dag in the deployment, with no filter restricting them to the Dags the caller is authorized to read. Any authenticated user holding asset-read access could therefore enumerate asset events — including the source Dag ID, task ID, run ID and event timestamps — for Dags they have no permission to see. Because the filter was also absent from the count query, `total_entries` and pagination disclosed the existence of hidden Dags even without inspecting individual rows. Deployments are affected whenever per-Dag access control is used to separate teams or tenants; no special configuration is required. Upgrade to apache-airflow 3.3.2 or later.","aliases":["CVE-2026-75158","PYSEC-2026-3988"],"modified":"2026-09-26T09:25:57.169604103Z","published":"2026-09-26T08:41:40.516Z","database_specific":{"cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/09/21/3"},{"type":"ADVISORY","url":"https://github.com/apache/airflow/pull/71741"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/rx5lg86l0qkjl2s7dtmpqxjq0xplr4fy"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75158"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-75158.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.9.0"}
