CVE-2026-75157: CWE-863: Incorrect Authorization in Apache Software Foundation Apache Airflow
CVE-2026-75157 is an authorization vulnerability in Apache Airflow affecting the DELETE endpoints for queued asset events. The flaw allows any authenticated user with read access to a DAG to delete that DAG's queued asset events, an action that should require edit permissions. This can silently suppress asset-triggered scheduling, impacting deployments using this feature. The issue affects versions prior to 3.3.2. Upgrading to Apache Airflow 3.3.2 or later resolves the vulnerability.
AI Analysis
Technical Summary
Apache Airflow's DELETE endpoints for queued asset events incorrectly check for read permission on a DAG instead of the required edit permission. This improper authorization allows authenticated users with read access to delete queued asset events for that DAG, which is a state-changing operation normally restricted to users with edit rights. The vulnerability impacts deployments using asset-triggered scheduling when DAG read access is granted more broadly than edit access, which is typical in RBAC configurations. The issue is fixed in Apache Airflow version 3.3.2.
Potential Impact
Authenticated users with read access to a DAG can delete queued asset events, thereby suppressing asset-triggered scheduling for that DAG. This unauthorized state change could disrupt workflow scheduling and execution in affected Airflow deployments. No special configuration is required for exploitation beyond the normal RBAC setup where read access is more permissive than edit access.
Mitigation Recommendations
Upgrade Apache Airflow to version 3.3.2 or later to address this authorization flaw. No other mitigations are indicated by the vendor advisory.
