Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Insecure File Permissions: Writing sensitive output files, such as S3 Select streams or MFA bootstrap configurations, without restricting local file permissions (0600) allows local unauthorized users to access secrets or tamper with data.

INI Injection: Failing to sanitize configuration values written to the AWS configuration file allows attackers to inject arbitrary INI sections and configuration parameters via newline injection in `aws configure set`.

Insecure Defaults: Wrapping SSH commands with permissive host key checking defaults (StrictHostKeyChecking=no) risks exposing management sessions to machine-in-the-middle (MitM) attacks.
