Missing Authentication for Critical Function in Apache Airflow
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | apache-airflow | >= 2.0.0, < 2.1.3 | 2.1.3 |
Details
As written in the advisory (Markdown source, shown as plain text).
The variable import endpoint was not protected by authentication in Airflow >=2.0.0, <2.1.3. This allowed unauthenticated users to hit that endpoint to add/modify Airflow variables used in DAGs, potentially resulting in a denial of service, information disclosure or remote code execution. This issue affects Apache Airflow >=2.0.0, <2.1.3.
