Name of the Vulnerable Software and Affected Versions apache-airflow-providers-fab versions prior to 3.6.4

Description Apache Airflow FAB Auth Manager is subject to an LDAP filter injection, which occurs when user-supplied input is improperly sanitized before being used in an LDAP filter. This allows unauthenticated attackers to bypass authentication or exfiltrate sensitive directory data.

Recommendations Update to apache-airflow-providers-fab version 3.6.4 or later. As a temporary workaround, disable LDAP authentication until the provider can be updated.
