CVE-2026-25219 [MEDIUM] CWE-200 CVE-2026-25219: The `access_key` and `connection_string` connection properties were not marked as sensitive names in The `access_key` and `connection_string` connection properties were not marked as sensitive names in secrets masker. This means that user with read permission could see the values in Connection UI, as well as when Connection was accidentaly logged to logs, those values could be seen in the logs. Azure Service Bus used those properties to store sensi

CVE-2023-51702 [MEDIUM] CWE-312 CVE-2023-51702: Since version 5.2.0, when using deferrable mode with the path of a Kubernetes configuration file for Since version 5.2.0, when using deferrable mode with the path of a Kubernetes configuration file for authentication, the Airflow worker serializes this configuration file as a dictionary and sends it to the triggerer by storing it in metadata without any encryption. Additionally, if used with an Airflow version between 2.3.0 and 2.6.0, the configura

CVE-2023-42792 [MEDIUM] CWE-668 CVE-2023-42792: Apache Airflow, in versions prior to 2.7.2, contains a security vulnerability that allows an authent Apache Airflow, in versions prior to 2.7.2, contains a security vulnerability that allows an authenticated user with limited access to some DAGs, to craft a request that could give the user write access to various DAG resources for DAGs that the user had no access to, thus, enabling the user to clear DAGs they shouldn't. Users of Apache Airflow are

CVE-2023-50783 [MEDIUM] CWE-284 CVE-2023-50783: Apache Airflow, versions before 2.8.0, is affected by a vulnerability that allows an authenticated u Apache Airflow, versions before 2.8.0, is affected by a vulnerability that allows an authenticated user without the variable edit permission, to update a variable. This flaw compromises the integrity of variable management, potentially leading to unauthorized data modification. Users are recommended to upgrade to 2.8.0, which fixes this issue

CVE-2025-54831 [MEDIUM] CWE-213 CVE-2025-54831: Apache Airflow 3 introduced a change to the handling of sensitive information in Connections. The in Apache Airflow 3 introduced a change to the handling of sensitive information in Connections. The intent was to restrict access to sensitive connection fields to Connection Editing Users, effectively applying a "write-only" model for sensitive values. In Airflow 3.0.3, this model was unintentionally violated: sensitive connection information could

CVE-2025-65995 [MEDIUM] CWE-209 CVE-2025-65995: When a DAG failed during parsing, Airflow’s error-reporting in the UI could include the full kwargs When a DAG failed during parsing, Airflow’s error-reporting in the UI could include the full kwargs passed to the operators. If those kwargs contained sensitive values (such as secrets), they might be exposed in the UI tracebacks to authenticated users who had permission to view that DAG. The issue has been fixed in Airflow 3.1.4 and 2.11.1, and use

CVE-2020-17511 [MEDIUM] CWE-312 CVE-2020-17511: In Airflow versions prior to 1.10.13, when creating a user using airflow CLI, the password gets logg In Airflow versions prior to 1.10.13, when creating a user using airflow CLI, the password gets logged in plain text in the Log table in Airflow Metadatase. Same happened when creating a Connection with a password field.

CVE-2023-42663 [MEDIUM] CWE-200 CVE-2023-42663: Apache Airflow, versions before 2.7.2, has a vulnerability that allows an authorized user who has ac Apache Airflow, versions before 2.7.2, has a vulnerability that allows an authorized user who has access to read specific DAGs only, to read information about task instances in other DAGs. Users of Apache Airflow are advised to upgrade to version 2.7.2 or newer to mitigate the risk associated with this vulnerability.

CVE-2023-35005 [MEDIUM] CWE-200 CVE-2023-35005: In Apache Airflow, some potentially sensitive values were being shown to the user in certain situati In Apache Airflow, some potentially sensitive values were being shown to the user in certain situations. This vulnerability is mitigated by the fact configuration is not shown in the UI by default (only if `[webserver] expose_config` is set to `non-sensitive-only`), and not all uncensored values are actually sentitive. This issue affects Apache A
