CVE-2023-49920 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. Apache Airflow, version 2.7.0 through 2.7.3, has a vulnerability that allows an attacker to trigger a DAG in a GET request without CSRF validation. As a result, it was possible for a malicious website opened in the same browser - by the user who also had Airflow UI opened - to trigger the execution of DAGs without the user's consent. Users are advised to upgrade to version 2.8.0 or later which is not affected. EPSS estimates a 1.03% chance of exploitation in the next 30 days.
