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...

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-2026-68970 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...

BIT-AIRFLOW-2026-68076 Apache Airflow: Connections test API: team-scope guard bypass resolves another team's environment Connection

Apache Airflow's environment-variable secrets backend resolved a team-scoped Connection or Variable from the wrong team's scope. The guard meant to prevent this only ran when no team scope was supplied, and its pattern could not match a team name containing an underscore, which team names are...

BIT-AIRFLOW-2026-59244 Apache Airflow: Secrets masker: `var.json` Variable values not masked in the Rendered Templates UI

Apache Airflow's secrets masker did not mask var.json Variable values whose value is a dict in the Rendered Templates UI — the dict value failed an isinstancestr guard — so a secret stored as a JSON Variable and referenced in a template via var.json was displayed in cleartext to any user with...

BIT-AIRFLOW-2026-58076 Apache Airflow: Unguarded import_string() of airflow_exc_ser / base_exc_ser exception nodes in BaseSerialization.deserialize enables DAG-author RCE on Scheduler / API Server

Apache Airflow's serialization layer reconstructed exception nodes by calling importstring on a class name taken from the serialized blob and instantiating it with arguments from the same blob, with no restriction on what could be imported. An operator's executorconfig reaches that branch, so a D...

BIT-AIRFLOW-2026-54183 Apache Airflow: Airflow Variables were not masked in the UI for authenticated users

Apache Airflow's secrets masker hides values stored under sensitive key names when they are displayed in the UI. The masker's recursion-depth limit did not descend into values nested inside a list, tuple, or set beyond that limit, so an Airflow Variable holding such a deeply-nested value was show...
