Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.2, Glances web server runs without authentication by default when started with `glances -w`, exposing REST API with sensitive system information including process command-lines containing credentials (passwords, API keys, tokens) to any network client. Version 4.5.2 fixes the issue.

Affected: PyPI: Glances

### Summary Glances web server runs without authentication by default when started with `glances -w`, exposing REST API with sensitive system information including process command-lines containing credentials (passwords, API keys, tokens) to any network client.

### Details Root Cause: Authentication is optional and disabled by default. When no password is provided, the API router initializes without authentication dependency, and the server binds to 0.0.0.0 exposing all endpoints.
