CVE-2025-14503

7.2 HIGH
Published: December 15, 2025 Modified: December 17, 2025

Description

An overly-permissive IAM trust policy in the Harmonix on AWS framework may allow IAM principals in the same AWS account to escalate privileges via role assumption. The sample code for the EKS environment provisioning role is configured to trust the account root principal, which may enable any IAM principal in the same AWS account with sts:AssumeRole permissions to assume the role with administrative privileges. We recommend customers upgrade to Harmonix on AWS v0.4.2 or later if you have deployed the framework using versions v0.3.0 through v0.4.1.
