A security vulnerability in the hulumi infrastructure toolkit for Pulumi allows authenticated users to impact infrastructure integrity due to insufficient configuration security.

The vulnerability relates to insufficient technical documentation and configuration practices (CWE-1059), which can be leveraged by an authenticated user to perform unauthorized modifications to infrastructure components.

With a CVSS score of 7.1, this vulnerability poses a high risk to cloud and platform infrastructure integrity. Successful exploitation could allow an authenticated attacker to manipulate infrastructure components, potentially leading to unauthorized resource provisioning or the modification of secure-by-default configurations.

Immediate Action: Update the @hulumi/baseline package to version 1.4.0 or later to ensure secure configurations.

Proactive Monitoring: Audit infrastructure deployment logs and Pulumi state files for any unauthorized changes or deviations from established security baselines.

Compensating Controls: Implement strict Role-Based Access Control (RBAC) for all users permitted to manage infrastructure deployments to minimize the risk of unauthorized modifications.

Public Exploit Available: Unknown.

The update to version 1.4.0 is mandatory for all users of the hulumi toolkit to ensure that infrastructure components are configured securely. Administrators should verify their deployment pipelines to confirm the update has been successfully integrated and that no unauthorized changes have occurred in the interim.
