CVE-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...

CVE-2026-68968

The CVE affects Apache Airflow (Backfill API). A mismatch between dependency parsing and endpoint validation for backfill_id (int() vs NonNegativeInt) allows an authenticated user with edit rights on one Dag to read, pause, and cancel backfills for other Dags. FastAPI resolves dependencies before...
