CVE-2026-75157 PUBLISHED

Apache Airflow: Asset queued-events DELETE endpoints gated on Dag READ instead of Dag EDIT (asset-triggered scheduling suppression)

Assigner: apache
Reserved: 17.08.2026 Published: 18.09.2026 Updated: 18.09.2026

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.
