Apache Airflow Providers OpenSearch: OpenSearch task-log handler leaks credentials embedded in the host URL_CVE-2026-43826

{
    "lastseen": "",
    "description": "The OpenSearch logging provider, when configured with a `host` URL that embeds credentials (for example `https://user:[email protected]:9200`), wrote the full host URL \u2014 including the embedded credentials \u2014 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.",
