Exposure of Sensitive System Information to an Unauthorized Control Sphere Affecting cdk package, versions >=2.172.0 <2.178.2

cdk is an AWS CDK Toolkit

Affected versions of this package are vulnerable to Exposure of Sensitive System Information to an Unauthorized Control Sphere through the expiration property in the credentials object. An attacker can gain access to AWS credentials by configuring a credential plugin to include this property.

Note:

Plugins that omit the expiration property are not vulnerable by this issue.

Remove the expiration property from the object returned by the plugin.

Note that this will prevent the CDK CLI from refreshing the credentials when needed, and may cause your workflow to fail on an expired credentials error.
