How to Fix GHSA-g43v-9x7q-83pq

To remediate this vulnerability, upgrade all affected @hulumi/policies dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@hulumi/policies fixed: 1.3.2 
npm install @hulumi/policies@1.3.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @hulumi/policies

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-g43v-9x7q-83pq, inspect your project dependencies using npm:

npm ls @hulumi/policies

Analyze the terminal output to locate any version of @hulumi/policies in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.2), your application is affected.

Note: The npm ls @hulumi/policies command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In @hulumi/policies, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Impact: @hulumi/policies versions before 1.3.2 could accept spoofed SecureBucket parent evidence for HULUMI-H1, allowing policy evaluation to miss an unsafe bucket shape. Patched in 1.3.2: the validator now correlates evidence to the expected component/resource relationship and includes regression coverage. Remediation: upgrade @hulumi/policies to 1.3.2 or later.
