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 change identities and their permissions
Grants 1 permissions management action on IAM, IAM Identity Center or Organizations, on any resource with no condition.
iam:passrole
Use with caution: Grant it only to identity administrators, and protect your admin roles and SCPs with a permissions boundary or an SCP of their own.
High
Can launch resources that run as a more privileged role
Grants every action of 9 documented escalation paths on any resource with no condition.
- cloudformation-001iam:PassRole + cloudformation:CreateStackunrestricted
- ecs-001iam:PassRole + ecs:CreateCluster + ecs:RegisterTaskDefinition + ecs:CreateServiceunrestricted
- ecs-002iam:PassRole + ecs:CreateCluster + ecs:RegisterTaskDefinition + ecs:RunTaskunrestricted
- ecs-003iam:PassRole + ecs:RegisterTaskDefinition + ecs:CreateServiceunrestricted
- ecs-004iam:PassRole + ecs:RegisterTaskDefinition + ecs:RunTaskunrestricted
- ecs-005iam:PassRole + ecs:RegisterTaskDefinition + ecs:StartTaskunrestricted
- ecs-007iam:PassRole + ecs:StartTask + ecs:RegisterContainerInstanceunrestricted
- ecs-008iam:PassRole + ecs:RunTaskunrestricted
1 more path
- ecs-009iam:PassRole + ecs:StartTaskunrestricted
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 2 documented escalation paths on any resource with no condition.
- cloudformation-002cloudformation:UpdateStackunrestricted
- 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
Full access to 2 services on every resource
Uses ecs:*, elasticloadbalancing:* with Resource "*" and no condition, so every action AWS adds to those services later is granted too.
ecs:*elasticloadbalancing:*
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.
