Affected packages

• npm @hulumi/policies: < 1.3.2 → fixed in 1.3.2

Description

Impact: @hulumi/policies versions before 1.3.2 only checked exact AWS IAM StringLike/StringEquals condition operator keys in G_OIDC_1. Set-qualified operators such as ForAnyValue:StringLike could hide wildcard GitHub Actions OIDC sub conditions from the mandatory guardrail. Patched in 1.3.2: the AWS trust-policy inspector now evaluates set-qualified string operators and rejects unsafe GitHub OIDC sub conditions. Remediation: upgrade @hulumi/policies to 1.3.2 or later.
