PYSEC-2026-22

Vulnerability from pysec - Published: 2026-05-11 09:16 - Updated: 2026-05-20 09:18

Details

The Elasticsearch 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-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.
