0Xt4Req

The issue is related to insufficient authentication of executed requests in Apache Airflow, allowing an attacker to trigger a DAG in a GET request without CSRF validation. This could enable a malicious website opened in the same browser as the Airflow UI to trigger the execution of DAGs without the user's consent.

The issue occurs when creating a note file with HTML in the Nextcloud Notes app. Instead of offering the file for download, the content is rendered in the preview. This affects versions prior to 4.8.0. No known workarounds are available for this issue.
