message: >-
The application creates a database connection with an empty password.
This can lead to unauthorized access by either an internal or external
malicious actor. To prevent this vulnerability, enforce authentication
when connecting to a database by using environment variables to securely
provide credentials or retrieving them from a secure vault or HSM
(Hardware Security Module).
note: >-
[CWE-287] Improper Authentication.
