Risk

High

An unrestricted escalation path, identity administration, secret reads or the power to switch off security monitoring. Read from this policy document alone: trust policies, boundaries and SCPs in your account still decide what actually succeeds. How this is assessed

High
Can launch resources that run as a more privileged role
Grants every action of 1 documented escalation path on any resource with no condition, and 3 more in a scoped form.
- cloudformation-005cloudformation:CreateChangeSet + cloudformation:ExecuteChangeSetunrestricted
- cloudformation-001iam:PassRole + cloudformation:CreateStackscoped
  - iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/service-role/AWSDeepRacerLambdaAccessRole
- cloudformation-003iam:PassRole + cloudformation:CreateStackSet + cloudformation:CreateStackInstancesscoped
  - iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/service-role/AWSDeepRacerLambdaAccessRole
- cloudformation-004iam:PassRole + cloudformation:UpdateStackSetscoped
  - iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/service-role/AWSDeepRacerLambdaAccessRole
Use with caution: Make sure no highly privileged role trusts the service involved, and restrict iam:PassRole in your own policies or boundary to named roles with iam:PassedToService.
High
Can take over existing resources that run as another role
Grants every action of 1 documented escalation path on any resource with no condition, and 1 more in a scoped form.
- cloudformation-002cloudformation:UpdateStackunrestricted
- lambda-003lambda:UpdateFunctionCodescoped
  - lambda:UpdateFunctionCode: on arn:aws:lambda:*:*:function:*DeepRacer*, arn:aws:lambda:*:*:function:*Deepracer*, arn:aws:lambda:*:*:function:*deepracer*
Use with caution: List the roles attached to the functions, instances, pipelines or notebooks it can modify: the holder effectively has them too.
Medium
Can rewrite resource policies and sharing
Grants 1 permissions management action across 1 service (cloudformation) on any resource, enough to share resources outside the account.
cloudformation:setstackpolicy
Use with caution: Turn on IAM Access Analyzer external access findings, and keep account-level guards like S3 Block Public Access enabled.
Medium
Full cloudformation access on every resource
Uses cloudformation:* with Resource "*" and no condition, so every action AWS adds to that service later is granted too.
cloudformation:*
Use with caution: The grant grows every time the service does. For long-lived access, prefer a policy that lists the actions you actually need.
