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 take over existing resources that run as another role
Grants every action of 3 documented escalation paths on any resource with no condition.
- cloudformation-002cloudformation:UpdateStackunrestricted
- codedeploy-001codedeploy:CreateDeploymentunrestricted
- ecs-006ecs:ExecuteCommand + ecs:DescribeTasksunrestricted
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 launch resources that run as a more privileged role
Grants the actions of 10 documented escalation paths, but only on named resources or under a condition. Review that scope before trusting it.
- cloudformation-001iam:PassRole + cloudformation:CreateStackscoped
  - iam:PassRole: condition iam:PassedToService
- ec2-001iam:PassRole + ec2:RunInstancesscoped
  - iam:PassRole: condition iam:PassedToService
- ecs-001iam:PassRole + ecs:CreateCluster + ecs:RegisterTaskDefinition + ecs:CreateServicescoped
  - iam:PassRole: condition iam:PassedToService
- ecs-002iam:PassRole + ecs:CreateCluster + ecs:RegisterTaskDefinition + ecs:RunTaskscoped
  - iam:PassRole: condition iam:PassedToService
- ecs-003iam:PassRole + ecs:RegisterTaskDefinition + ecs:CreateServicescoped
  - iam:PassRole: condition iam:PassedToService
- ecs-004iam:PassRole + ecs:RegisterTaskDefinition + ecs:RunTaskscoped
  - iam:PassRole: condition iam:PassedToService
- ecs-005iam:PassRole + ecs:RegisterTaskDefinition + ecs:StartTaskscoped
  - iam:PassRole: condition iam:PassedToService
- ecs-007iam:PassRole + ecs:StartTask + ecs:RegisterContainerInstancescoped
  - iam:PassRole: condition iam:PassedToService
2 more paths
- ecs-008iam:PassRole + ecs:RunTaskscoped
  - iam:PassRole: condition iam:PassedToService
- ecs-009iam:PassRole + ecs:StartTaskscoped
  - 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.
Medium
Full ecs access on every resource
Uses ecs:* with Resource "*" and no condition, so every action AWS adds to that service later is granted too.
ecs:*
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.
