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 3 documented escalation paths on any resource with no condition.
- ec2-001iam:PassRole + ec2:RunInstancesunrestricted
- ec2-003iam:PassRole + ec2:RequestSpotInstancesunrestricted
- emr-001iam:PassRole + elasticmapreduce:RunJobFlowunrestricted
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.
- ec2-002ec2:ModifyInstanceAttribute + ec2:StopInstances + ec2:StartInstancesunrestricted
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 22 permissions management actions across 3 services (cloudwatch, elasticmapreduce, s3) on any resource, enough to share resources outside the account.
cloudwatch:assumeaccessprofilecloudwatch:createaccessgrantcloudwatch:createaccessprofilecloudwatch:createdomainaccessgrantfororganizationcloudwatch:deleteaccessgrantcloudwatch:deleteaccessprofilecloudwatch:deletedomainaccessgrantfororganizationcloudwatch:updateaccessprofileelasticmapreduce:deleteworkspaceaccesselasticmapreduce:putblockpublicaccessconfigurationelasticmapreduce:putworkspaceaccesss3:putaccessgrantsinstanceresourcepolicyand 10 more
Use with caution: Turn on IAM Access Analyzer external access findings, and keep account-level guards like S3 Block Public Access enabled.
Medium
Can read data in every bucket or table
Reads any object in any S3 bucket; any DynamoDB table. Read-only is not the same as harmless when the data is the asset.
s3:GetObject (via s3:Get*)dynamodb:Scandynamodb:GetItem
Use with caution: Read access to data is still access to data. For people who only need to see configuration, ViewOnlyAccess carries none of these signals.
Medium
Full access to 2 services on every resource
Uses cloudwatch:*, elasticmapreduce:* with Resource "*" and no condition, so every action AWS adds to those services later is granted too.
cloudwatch:*elasticmapreduce:*
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.
