CVE-2026-59245: CWE-269: Improper Privilege Management in Apache Software Foundation Apache Airflow FAB provider
A privilege escalation vulnerability exists in the Apache Airflow FAB provider where a DAG named 'DAGs' causes a resource name collision. This collision grants users with per-DAG access to that specific DAG unintended global all-DAGs permissions, allowing read and edit access to every DAG. The issue affects versions prior to 3.7.2. The vendor advises upgrading to version 3.7.2 or later to resolve this issue by disambiguating the resource names.
AI Analysis
Technical Summary
In Apache Airflow FAB auth manager, a DAG with the identifier 'DAGs' conflicts with the global all-DAGs permission resource name generated by the resource_name() function. This naming collision results in users granted per-DAG access to the 'DAGs' DAG receiving unintended global permissions across all DAGs, effectively escalating their privileges. The vulnerability is addressed in apache-airflow-providers-fab version 3.7.2 and later, which corrects the resource name collision.
Potential Impact
Users with per-DAG access to a DAG named 'DAGs' can gain unauthorized read and edit permissions on all DAGs in the system, leading to privilege escalation. This could allow lower-privileged users to access and modify workflows beyond their intended scope.
Mitigation Recommendations
Upgrade apache-airflow-providers-fab to version 3.7.2 or later, which fixes the resource name collision causing the privilege escalation. No other mitigation steps are indicated by the vendor advisory.
