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.
- ec2-001iam:PassRole + ec2:RunInstancesscoped
  - iam:PassRole: condition iam:PassedToService
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.

IAM Access Analyzer (1)

Suggestion / EQUIVALENT_TO_NULL_FALSE
We recommend replacing the key aws:RequestTag/CreatedByLaunchTemplateVersion in the condition block of StringLike with {aws:RequestTag/CreatedByLaunchTemplateVersion: false} to ensure better enforcement of the condition. AWS docs
