{"id":"PYSEC-2026-23","details":"The OpenSearch logging provider, when configured with a `host` URL that embeds credentials (for example `https://user:password@server.example.com:9200`), wrote the full host URL — including the embedded credentials — into task logs. Any user with task-log read permission could harvest the backend credentials. Users are advised to upgrade to `apache-airflow-providers-opensearch` 1.9.1 or later and, as a defense-in-depth measure, configure the backend credentials via a secret backend rather than embedding them in the `[opensearch] host` URL.","aliases":["CVE-2026-43826","GHSA-xccp-97wp-3gjg"],"modified":"2026-06-10T17:00:05.436540126Z","published":"2026-05-11T09:16:26.143Z","references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/05/10/2"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/bxsrqx1vwssovnwnrvgh9xcosptmf73y"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/65509"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-xccp-97wp-3gjg"}],"affected":[{"package":{"name":"apache-airflow-providers-opensearch","ecosystem":"PyPI","purl":"pkg:pypi/apache-airflow-providers-opensearch"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.1"}]}],"versions":["1.0.0","1.0.0rc1","1.1.0","1.1.0rc1","1.1.1","1.1.1rc1","1.1.2","1.1.2rc1","1.2.0","1.2.0rc1","1.2.1","1.2.1rc1","1.3.0","1.3.0rc1","1.4.0","1.4.0rc1","1.5.0","1.5.0rc1","1.6.0","1.6.0rc1","1.6.0rc2","1.6.1","1.6.1rc1","1.6.2","1.6.2rc1","1.6.3","1.6.3rc1","1.7.0","1.7.0rc1","1.7.1","1.7.1rc1","1.7.2","1.7.2rc1","1.7.3","1.7.3rc1","1.7.4","1.7.4rc1","1.7.5","1.7.5rc1","1.8.0","1.8.0rc1","1.8.1","1.8.1rc1","1.8.2","1.8.2rc1","1.8.3","1.8.3rc1","1.8.4","1.8.4rc1","1.8.5","1.8.5rc1","1.9.0","1.9.0rc1","1.9.1rc1"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/apache-airflow-providers-opensearch/PYSEC-2026-23.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
