CVE-2026-75157
Published:September 18, 2026
Updated:September 22, 2026
Apache Airflow's asset queued-events DELETE endpoints checked the caller's Dag-axis permission with "READ" instead of "EDIT". Any authenticated user who could read a Dag could therefore delete that Dag's queued asset events, silently suppressing asset-triggered scheduling for it — a state-changing action gated on a read-only permission. Deployments are affected whenever asset-triggered scheduling is in use and Dag read access is granted more widely than Dag edit access, which is the normal RBAC arrangement; no special configuration is required. Upgrade to apache-airflow 3.3.2 or later.
