HCL DFXAnalytics is affected by a Missing HTTP Strict-Transport-Security Header vulnerability. The application fails to implement the HTTP Strict Transport Security (HSTS) policy within its responses, which could allow a remote attacker to downgrade the communication channel to an unencrypted connection (HTTP) and conduct man-in-the-middle (MitM) attacks. To remediate this, the application must include the "Strict-Transport-Security" header in all web application responses.
