This critical vulnerability affects @hulumi/policies versions before 1.3.2, allowing attackers to craft admin-equivalent policy paths that bypass policy evaluation controls due to incomplete inspection of inline and attached IAM policy evidence. Organizations should verify their policies, consider updating to version 1.3.2 or later, and monitor for suspicious policy evaluation bypass attempts. Evidence is limited; further verification is recommended.

Who should care

Organizations using @hulumi/policies, especially those with critical IAM policy evaluations, should be aware of this vulnerability and take immediate action to inspect and potentially update their policies. This includes reviewing IAM policy evidence for admin-equivalent paths and considering updates to @hulumi/policies version 1.3.2 or later. Security teams and operators should prioritize this vulnerability due to its critical severity and potential impact on policy evaluation controls.

Technical summary

@hulumi/policies versions before 1.3.2 fail to fully inspect inline and attached IAM policy evidence for the administrator-policy guardrail, allowing attackers to craft admin-equivalent policy paths that bypass policy evaluation controls. This vulnerability affects organizations using @hulumi/policies, especially those with critical IAM policy evaluations.

Defensive priority

Organizations using @hulumi/policies versions before 1.3.2 should prioritize immediate inspection and potential updates to ensure admin-equivalent policy paths are not being exploited.

Recommended defensive actions

  • Inventory @hulumi/policies versions and verify if running versions before 1.3.2.
  • Inspect IAM policy evidence for admin-equivalent paths.
  • Consider updating to @hulumi/policies version 1.3.2 or later.
  • Monitor for suspicious policy evaluation bypass attempts.
  • Implement compensating controls for IAM policy evaluation.
