PYSEC-2026-3711

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...

PYSEC-2026-3709

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...

PYSEC-2026-3708

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...

PYSEC-2026-3707

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...

PYSEC-2026-3993

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...

PYSEC-2026-3706

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...

PYSEC-2026-3992

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 ...

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...

PYSEC-2026-3705

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...

PYSEC-2026-3714

The Google Cloud Secret Manager secrets backend in Apache Airflow's Google provider never applied the team scope when resolving Connections and Variables: the caller's teamname was accepted by the backend but dropped at the internal call boundary, so every lookup resolved against the team-agnosti...

PYSEC-2026-3715

The Yandex Lockbox secrets backend in Apache Airflow's Yandex provider resolved a team-scoped Connection or Variable id through the team-agnostic lookup when the team-scoped lookup missed. In a deployment running multi-team mode with this backend, a caller in one team could resolve a secret...
