CVE-2021-35936 [MEDIUM] CWE-200 CVE-2021-35936: If remote logging is not used, the worker (in the case of CeleryExecutor) or the scheduler (in the c If remote logging is not used, the worker (in the case of CeleryExecutor) or the scheduler (in the case of LocalExecutor) runs a Flask logging server and is listening on a specific port and also binds on 0.0.0.0 by default. This logging server had no authentication and allows reading log files of DAG jobs. This issue affects Apache Airflow < 2.1.2.

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.

Same happened when creating a Connection with a password field.

CVE-2020-17513 [MEDIUM] CWE-918 CVE-2020-17513: In Apache Airflow versions prior to 1.10.13, the Charts and Query View of the old (Flask-admin based In Apache Airflow versions prior to 1.10.13, the Charts and Query View of the old (Flask-admin based) UI were vulnerable for SSRF attack.

CVE-2020-13944 [MEDIUM] CWE-79 CVE-2020-13944: In Apache Airflow < 1.10.12, the "origin" parameter passed to some of the endpoints like '/trigger' In Apache Airflow < 1.10.12, the "origin" parameter passed to some of the endpoints like '/trigger' was vulnerable to XSS exploit.

CVE-2020-11981 [CRITICAL] CWE-78 CVE-2020-11981: 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 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.

CVE-2020-11978 [HIGH] CWE-78 CVE-2020-11978: An issue was found in Apache Airflow versions 1.10.10 and below. A remote code/command injection vul An issue was found in Apache Airflow versions 1.10.10 and below. A remote code/command injection vulnerability was discovered in one of the example DAGs shipped with Airflow which would allow any authenticated user to run arbitrary commands as the user running airflow worker/scheduler (depending on the executor in use). If you already have examples dis

CVE-2020-11983 [MEDIUM] CWE-79 CVE-2020-11983: An issue was found in Apache Airflow versions 1.10.10 and below. It was discovered that many of the An issue was found in Apache Airflow versions 1.10.10 and below. It was discovered that many of the admin management screens in the new/RBAC UI handled escaping incorrectly, allowing authenticated users with appropriate permissions to create stored XSS attacks.

CVE-2018-20244 [MEDIUM] CWE-79 CVE-2018-20244: In Apache Airflow before 1.10.2, a malicious admin user could edit the state of objects in the Airfl In Apache Airflow before 1.10.2, a malicious admin user could edit the state of objects in the Airflow metadata database to execute arbitrary javascript on certain page views.

CVE-2017-17836 [CRITICAL] CWE-255 CVE-2017-17836: In Apache Airflow 1.8.2 and earlier, an experimental Airflow feature displayed authenticated cookies In Apache Airflow 1.8.2 and earlier, an experimental Airflow feature displayed authenticated cookies, as well as passwords to databases used by Airflow. An attacker who has limited access to airflow, whether it be via XSS or by leaving a machine unlocked can exfiltrate all credentials from the system.

CVE-2018-20245 [HIGH] CWE-295 CVE-2018-20245: The LDAP auth backend (airflow.contrib.auth.backends.ldap_auth) prior to Apache Airflow 1.10.1 was m The LDAP auth backend (airflow.contrib.auth.backends.ldap_auth) prior to Apache Airflow 1.10.1 was misconfigured and contained improper checking of exceptions which disabled server certificate checking.

CVE-2017-15720 [HIGH] CWE-20 CVE-2017-15720: In Apache Airflow 1.8.2 and earlier, an authenticated user can execute code remotely on the Airflow In Apache Airflow 1.8.2 and earlier, an authenticated user can execute code remotely on the Airflow webserver by creating a special object.
