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 2 permissions management actions across 1 service (s3) on any resource, enough to share resources outside the account.
s3:putobjectacls3:putobjectversionacl
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.
