Upgrade apache-airflow-providers-fab to version 3.8.1 or higher.
Overview
apache-airflow-providers-fab is a Provider package apache-airflow-providers-fab for Apache Airflow
Affected versions of this package are vulnerable to Origin Validation Error due to missing issuer and audience validation in _decode_and_validate_azure_jwt in providers/fab/src/airflow/providers/fab/auth_manager/security_manager/override.py. An attacker can log in to the Airflow UI by supplying a correctly signed Azure AD id_token from a different tenant, including one they control, because the token is accepted after signature verification alone. The OAuth login path reads the identity and role data directly from that attacker-controlled token, so a deployment configured with Azure AD can grant access to an unauthorized user and expose the Airflow web UI to account takeover.
