CVE-2026-48892

The Config API in Apache Airflow fails to redact per-key secrets-backend overrides (e.g., AIRFLOW__SECRETS__BACKEND_KWARG__SECRET_ID) because these synthetic config options are missing from the sensitive_config_values list. This allows an authenticated UI/API user with Config read permission to r...

CVE-2026-68076

Apache Airflow's environment-variable secrets backend contains an authorization bypass where a team-scoped Connection or Variable can be resolved from the wrong team's scope. The root cause is a guard bypass occurring when a team name contains an underscore , causing the lookup to fall through to...

CVE-2026-25219

Apache Airflow is vulnerable because the access_key and connection_string properties were not marked as sensitive names in the secrets masker. This allows users with read permissions to view these values in the Connection UI . Additionally, if a Connection is accidentally logged, these sensitive ...

CVE-2026-40690

The Apache Airflow asset dependency graph fails to restrict nodes based on a viewer's DAG read permissions . This flaw allows a user with read access to at least one DAG to browse the asset graph for any other asset within the deployment, potentially revealing the existence and names of DAGs and ...

CVE-2025-54941

The CVE-2025-54941 issue affects Apache Airflow, specifically the example_dag_decorator parameter handling. A non-validated parameter in the example DAG allowed a UI user to redirect to a malicious server and execute code on a worker, but exploitation requires that example DAGs are enabled in pro...

CVE-2026-32690

In Apache Airflow , a flaw in the Variable response masker allows secrets stored as nested fields within JSON dictionaries to be exposed without proper redaction.

CVE-2026-28563

CVE-2026-28563 affects Apache Airflow, versions 3.1.0–3.1.7. The /ui/dependencies endpoint returns the full DAG dependency graph without filtering by authorized DAG IDs, allowing an authenticated user with only the DAG Dependencies permission to enumerate DAGs they are not authorized to view. Roo...

CVE-2026-41016

The Apache Airflow SMTP provider SmtpHook is vulnerable because it calls smtplib.SMTP.starttls() without an SSL context , leading to a lack of certificate validation during the TLS upgrade.
