Risk

Medium

The same capabilities in a scoped form, resource policy writes, reads across all data, or full access to a whole service. Read from this policy document alone: trust policies, boundaries and SCPs in your account still decide what actually succeeds. How this is assessed

Medium
Can launch resources that run as a more privileged role
Grants the actions of 1 documented escalation path, but only on named resources or under a condition. Review that scope before trusting it.
- cloudformation-005cloudformation:CreateChangeSet + cloudformation:ExecuteChangeSetscoped
  - cloudformation:CreateChangeSet: on arn:aws:cloudformation:*:*:stack/awseb-*, arn:aws:cloudformation:*:*:stack/eb-*
  - cloudformation:ExecuteChangeSet: on arn:aws:cloudformation:*:*:stack/awseb-*, arn:aws:cloudformation:*:*:stack/eb-*
Use with caution: Check which roles, users or policies fall inside the scope shown above. Within it the escalation works as documented, so keep privileged principals out of it.
