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 read secrets
Reads data encrypted with any KMS key whose key policy allows it, on any resource with no condition.
kms:Decrypt
Use with caution: Where the holder needs only some secrets, write your own policy scoped to their ARNs or tags, and limit decryption in the KMS key policies.
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.
