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 take over other users or roles
Grants the actions of 1 documented escalation path, but only on named resources or under a condition. Review that scope before trusting it.
- sts-001sts:AssumeRolescoped
  - sts:AssumeRole: condition aws:TagKeys, iam:ResourceTag/AmazonDataZoneProject
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.
