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-2026-65017 Apache Airflow: Config API: team-scoped Celery broker secret disclosed to a Viewer (multi-team masking bypass)

Apache Airflow's Config API did not mask team-scoped sensitive configuration values in multi-team deployments. When an administrator has enabled multi-team mode and exposed the Config API, an authenticated Viewer holding only configuration-read access — with no prior access to the secret — could...

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-2026-59242 Apache Airflow: Arbitrary airflow.* class instantiation on the API server via the XCom deserialize endpoint

Apache Airflow's XCom GET /api/v2/.../xcomEntries/key?deserialize=true endpoint passed a string-literal payload through BaseXCom.deserializevalue without the checkforbiddenxcomkeys guard, allowing an authenticated API user with XCom write-and-read access to instantiate arbitrary airflow. classes ...

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...

Apache Airflow's Backfill API authorized a request against a Dag id supplied by the caller whenever the backfill id 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...

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

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...

GHSA-5247-M8W9-2V4M Apache Airflow missing team context permits cross-team Dag actions and XCom reads

GHSA-F3C2-J7G8-VPP8 Apache Airflow Task SDK fails to mask list-shaped JSON Variables

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...

Insertion of Sensitive Information Into Sent Data

Overview Affected versions of this package are vulnerable to Insertion of Sensitive Information Into Sent Data in the Config API when multi-team mode is enabled and the API is exposed. An attacker can obtain sensitive team-scoped Celery broker credentials by accessing configuration-read endpoints...
