Improper Authentication in Apache Airflow
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | apache-airflow | >= 2.0.0, < 2.0.1rc1 | 2.0.1rc1 |
Details
As written in the advisory (Markdown source, shown as plain text).
The lineage endpoint of the deprecated Experimental API was not protected by authentication in Airflow 2.0.0. This allowed unauthenticated users to hit that endpoint. This is low-severity issue as the attacker needs to be aware of certain parameters to pass to that endpoint and even after can just get some metadata about a DAG and a Task. This issue only affects Apache Airflow 2.0.0.
