BREW-aws-cdk-CVE-2025-2598 — AWS CDK CLI prints AWS credentials retrieved by custom credential plugins

Affected: Homebrew: aws-cdk

When the AWS Cloud Development Kit (AWS CDK) Command Line Interface (AWS CDK CLI) is used with a credential plugin which returns an expiration property with the retrieved AWS credentials, the credentials are printed to the console output. To mitigate this issue, users should upgrade to version 2.178.2 or later and ensure any forked or derivative code is patched to incorporate the new fixes.

GHSA-v63m-x9r9-8gqp — AWS CDK CLI prints AWS credentials retrieved by custom credential plugins

Affected: npm: aws-cdk, npm: cdk

## Summary

The AWS Cloud Development Kit (AWS CDK) [1] is an open-source software development framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. The AWS CDK CLI [2] is a command line tool for interacting with CDK applications. Customers can use the CDK CLI to create, manage, and deploy their AWS CDK projects.

An issue exists in the AWS CDK CLI where, under certain conditions, AWS credentials may be returned in the console output. Plugins that return an `expiration `property in the credentials object are affected by this issue. Plugins that omit the `expiration` property are not affected.

## Impact

When customers run AWS CDK CLI commands with credential plugins and configure those plugins to return temporary credentials by including an `expiration` property, the AWS credentials retrieved by the plugin may be returned in the console output. Any user with access where the CDK CLI was ran would have access to this output.

The following are examples of configuring a custom credential plugin:

_Via command line option:_

`cdk deploy --plugin /path/to/plugin`

_Via configuration file [3]:_

```json { "plugin": "/path/to/plugin" } ```

Plugins that return an `expiration` property in the credentials object, such as the following example, are affected:

```console return { accessKeyId: '<access-key>', secretAccessKey: '<secret-access-key>', sessionToken: '<session-token>', expiration: <date>, }; ```

The `expi…
