Frequently Asked Questions

1

Which environments are exposed?

Environments using @hulumi/policies to apply security guardrails to GitHub OIDC trust policies are exposed if they use a version earlier than 1.3.2. The issue concerns validation of AWS IAM set-qualified condition operators in those policies.

2

What does an attacker need to bypass the guardrails?

The bypass relies on using a ForAnyValue:StringLike condition operator to conceal wildcard GitHub Actions OIDC subject conditions from the policy validation guardrails.

3

How can I determine whether I need to remediate?

Check the installed @hulumi/policies version. Versions before 1.3.2 are affected; upgrade to 1.3.2 or later.
