CVE-2026-41018

CVE-2026-41018 · Apache Airflow Providers Elasticsearch: Elasticsearch task-log handler leaks credentials embedded in the host URL

This page contains facts from public vulnerability sources. Check the original advisory before updating.

The Elasticsearch 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-elasticsearch` 6.5.3 or later and, as a defense-in-depth measure, configure the backend credentials via a secret backend rather than embedding them in the `[elasticsearch] host` URL.
