## Affected

- AWS aws-tools-for-powershell: through 5.0.305

## Description

Insertion of sensitive information into log file in AWS Tools for PowerShell before 5.0.306 might allow local users to recover an IAM user's cleartext AWS Management Console password from command output and log artifacts. To remediate this issue, users should upgrade to version 5.0.306 or later. After upgrading, review PowerShell transcripts and log stores for previously disclosed passwords and rotate any affected IAM console passwords.
