CVE-2021-28359 [MEDIUM] CVE-2021-28359: The "origin" parameter passed to some of the endpoints like '/trigger' was vulnerable to XSS exploit The "origin" parameter passed to some of the endpoints like '/trigger' was vulnerable to XSS exploit. This issue affects Apache Airflow versions <1.10.15 in 1.x series and affects 2.0.0 and 2.0.1 and 2.x series. This is the same as CVE-2020-13944 & CVE-2020-17515 but the implemented fix did not fix the issue completely. Update to Airflow 1.10.15 or 2.0.2. P

CVE-2021-26559 [MEDIUM] CWE-284 CVE-2021-26559: Improper Access Control on Configurations Endpoint for the Stable API of Apache Airflow allows users Improper Access Control on Configurations Endpoint for the Stable API of Apache Airflow allows users with Viewer or User role to get Airflow Configurations including sensitive information even when `[webserver] expose_config` is set to `False` in `airflow.cfg`. This allowed a privilege escalation attack. This issue affects Apache Airflow 2.0.0.

CVE-2021-26697 [MEDIUM] CWE-269 CVE-2021-26697: The lineage endpoint of the deprecated Experimental API was not protected by authentication in Airfl 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

CVE-2020-17526 [HIGH] CVE-2020-17526: Incorrect Session Validation in Apache Airflow Webserver versions prior to 1.10.14 with default conf Incorrect Session Validation in Apache Airflow Webserver versions prior to 1.10.14 with default config allows a malicious airflow user on site A where they log in normally, to access unauthorized Airflow Webserver on Site B through the session from Site A. This does not affect users who have changed the default value for `[webserver] secret_key` config.

When using CeleryExecutor, if an at An issue was found in Apache Airflow versions 1.10.10 and below. When using CeleryExecutor, if an attacker can connect to the broker (Redis, RabbitMQ) directly, it is possible to inject commands, resulting in the celery worker running arbitrary commands.

CVE-2020-11982 [CRITICAL] CWE-502 CVE-2020-11982: An issue was found in Apache Airflow versions 1.10.10 and below. When using CeleryExecutor, if an at An issue was found in Apache Airflow versions 1.10.10 and below. When using CeleryExecutor, if an attack can connect to the broker (Redis, RabbitMQ) directly, it was possible to insert a malicious payload directly to the broker which could lead to a deserialization attack (and thus remote code execution) on the Worker.
