The escalation triggers when a DAG named `DAGs` exists and a lower-privileged user is given per-DAG access to it, granting that user read/edit access to every DAG. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.2 or later, which disambiguates the resource-name collision.\n\n## Affected\n\n- `apache-airflow-providers-fab < 3.7.2`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `apache-airflow-providers-fab 3.7.2`","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
