Risk

Medium

The same capabilities in a scoped form, resource policy writes, reads across all data, or full access to a whole service. Read from this policy document alone: trust policies, boundaries and SCPs in your account still decide what actually succeeds. How this is assessed

Medium
Can rewrite resource policies and sharing
Grants 37 permissions management actions across 5 services (cloudwatch, dynamodb, s3, sns, sqs) on any resource, enough to share resources outside the account.

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:*)dynamodb:Scan (via dynamodb:*)dynamodb:GetItem (via dynamodb:*)
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 6 services on every resource
Uses cloudwatch:*, dynamodb:*, s3:*, sdb:*, sns:*, sqs:* with Resource "*" and no condition, so every action AWS adds to those services later is granted too.
cloudwatch:*dynamodb:*s3:*sdb:*sns:*sqs:*
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.
