# CVE-2026-107783 - Insertion of sensitive information into log file in AWS Tools for PowerShell

AWS Tools for PowerShell V5 up to 5.0.305 can write an IAM user's cleartext AWS Management Console password into command output and log artifacts. A local user who can read those logs or output can recover the password and sign in as that IAM user.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `Get-Module -ListAvailable AWSPowerShell.NetCore, AWS.Tools.Common` or `(Get-Module AWS.Tools.Common).Version` and compare against `5.0.306`
- Check whether scripts use `-WhatIf` or `-Confirm` with cmdlets that take passwords or other sensitive arguments, such as IAM login profile calls

## Fix

- Upgrade AWS Tools for PowerShell to `5.0.306` or later
- Patch any forked or derivative copies of the module to include the fix
- Until upgraded, avoid `-WhatIf` and `-Confirm` with cmdlets that carry sensitive arguments
- If a password may have been exposed, reset the affected IAM user's console password

Bulletin ID: 2026-132-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 10/09/2026 08:30 AM PDT

Description:

AWS Tools for PowerShell V5 lets developers and administrators manage their AWS services from the PowerShell scripting environment. We identified CVE-2026-107783, where 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.

Impacted versions: <= v5.0.305

Resolution:

This issue has been addressed in 5.0.306 version. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Workarounds:

Avoid using -WhatIf / -Confirm with cmdlets that contain sensitive information in its arguments when using AWS Tools for PowerShell in versions <= 5.0.305.
