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 switch off security monitoring
Can stop a CloudTrail trail, delete a CloudTrail trail, redirect or narrow a CloudTrail trail, change which events CloudTrail records, which is how an intruder hides.
cloudtrail:StopLogging (via cloudtrail:*)cloudtrail:DeleteTrail (via cloudtrail:*)cloudtrail:UpdateTrail (via cloudtrail:*)cloudtrail:PutEventSelectors (via cloudtrail:*)
Use with caution: Deny these actions with an SCP for everyone outside a break-glass role, so no single policy can blind you.
Medium
Can rewrite resource policies and sharing
Grants 2 permissions management actions across 2 services (s3, sns) on any resource, enough to share resources outside the account.
s3:putbucketpolicysns:addpermission
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. Read-only is not the same as harmless when the data is the asset.
s3:GetObject
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 cloudtrail access on every resource
Uses cloudtrail:* with Resource "*" and no condition, so every action AWS adds to that service later is granted too.
cloudtrail:*
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.
