CVE-2026-59242: Deserialization of Untrusted Data

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 ...

CVE-2026-58076: Deserialization of Untrusted Data

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...

CVE-2026-54183: Exposure of Sensitive Information to an Unauthorized Actor

Apache Airflow's secrets masker hides values stored under sensitive key names when they are displayed in the UI.
