AWS CLI Configuration: The AWS CLI (Command Line Interface) uses a configuration file to store access keys, region, and other settings. This file is usually located at ~/.aws/credentials for credentials and ~/.aws/config for configuration. The URL could be pointing to a non-standard location or a specific organizational setup.

Server-Side Request Forgery (SSRF) occurs when an application receives a user-supplied URL and processes it on the server side without proper validation. Attackers use this to:
