Summary of the Pull Request

The ImportKeyPair action in the context of Amazon Web Services (AWS) is used to import a public SSH key into your AWS account. This allows you to use an existing SSH key to access your EC2 instances.

If an attacker gains access to this function, they can:
• Import their own key: This would allow them to gain SSH access to instances associated with that key.
• Gain unauthorized access: Use the imported key to execute commands on the instances, potentially accessing sensitive data or disrupting services.
