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...

CVE-2026-67587: Deserialization of Untrusted Data

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...

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-2026-68968: Interpretation Conflict

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...
