Apache Airflow exposes sensitive JSON Variable values through the Bulk Variables API

The Bulk Variables API in Apache Airflow called the redactor without passing the variable's key, so the key-based shouldhidevalueforkey check which triggers on secret-suffixed key names like password / token / secret could not fire for JSON-decodable variable values. An authenticated UI/API user...

Apache Airflow <=1.10.10 - Remote Code Execution

Apache Airflow versions 1.10.10 and below are vulnerable to remote code/command injection vulnerabilities in one of the example DAGs shipped with Airflow. This could allow any authenticated user to run arbitrary commands as the user running airflow worker/scheduler depending on the executor in us...

CVE-2026-75156

Apache Airflow FAB provider versions 3.7.3 through 3.8.0 do not validate the issuer or audience of Azure AD idtokens during OAuth login. Deployments are affected only when the FAB auth manager is configured with Azure AD as an OAuth provider. Because the signing keys are fetched from Microsoft's...

BIT-AIRFLOW-2026-67587 Apache Airflow: DAG-author remote code execution on the Scheduler via a Serde `Callback` deserialization gadget

Apache Airflow's Task SDK rebuilt a Callback object from serialized data by re-running its constructor, which imports the module named by the stored callback path. Because SyncCallback is itself an Airflow class it passes the default alloweddeserializationclasses allow-list, so tightening that...

BIT-AIRFLOW-2026-67260 Apache Airflow: DAG-author remote code execution on the Scheduler via awaiting_input next_kwargs deserialization

Apache Airflow 3.3.0 moved human-in-the-loop tasks from the triggerer to a new awaitinginput task state swept by the scheduler. That sweep deserializes the task instance's nextkwargs without an allow-list, so a Dag author — who controls that value through the task execution API — can cause an...

BIT-AIRFLOW-2026-68971 Apache Airflow: Cross-team authorization bypass in the asset materialization and dag-run result endpoints

Apache Airflow's asset materialization endpoint POST /api/v2/assets/assetid/materialize and the XCom result check on waitdagrununtilfinished authorized the target Dag without its team, unlike every other authorization site. A team-aware auth manager distinguishes a team-scoped Dag from a global o...

BIT-AIRFLOW-2026-68970 Apache Airflow: Values of a list-shaped Variable are not masked in task logs and the Rendered Templates UI

Apache Airflow's Task SDK did not mask the contents of a Variable whose JSON value is a list, so secrets stored in that shape appeared in cleartext in task logs and in the Rendered Templates UI. Masking was applied only when the deserialized value was a string or a dict; a list at the top level...

BIT-AIRFLOW-2026-68969 Apache Airflow: Bulk Variable and Connection endpoints record secret values in the audit log in cleartext

Apache Airflow wrote Variable values and Connection extra contents to the audit log in cleartext when they were submitted through the bulk endpoints PATCH /api/v2/variables and PATCH /api/v2/connections. The audit-log masking recognised only top-level request fields, and a bulk request nests its...

BIT-AIRFLOW-2026-68968 Apache Airflow: Authorization bypass in the Backfill API through conflicting interpretations of the backfill id

Apache Airflow's Backfill API authorized a request against a Dag id supplied by the caller whenever the backfillid path segment failed to parse. The authorization dependency parsed it with int while the route handler parsed it as pydantic's NonNegativeInt, which accepts values int rejects 1.0...
