Apache Airflow Providers OpenSearch: OpenSearch task-log handler leaks credentials embedded in the host URL
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | apache-airflow-providers-opensearch | < 1.9.1 | 1.9.1 |
Details
As written in the advisory (Markdown source, shown as plain text).
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 — 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.
