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 switch off security monitoring
Can delete CloudWatch log groups, which is how an intruder hides.
logs:DeleteLogGroup (via logs:*)
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 12 permissions management actions across 3 services (cloudwatch, logs, sns) on any resource, enough to share resources outside the account.
cloudwatch:assumeaccessprofilecloudwatch:createaccessgrantcloudwatch:createaccessprofilecloudwatch:createdomainaccessgrantfororganizationcloudwatch:deleteaccessgrantcloudwatch:deleteaccessprofilecloudwatch:deletedomainaccessgrantfororganizationcloudwatch:updateaccessprofilelogs:deleteresourcepolicylogs:putresourcepolicysns:addpermissionsns:removepermission
Use with caution: Turn on IAM Access Analyzer external access findings, and keep account-level guards like S3 Block Public Access enabled.
Medium
Full access to 3 services on every resource
Uses cloudwatch:*, logs:*, sns:* with Resource "*" and no condition, so every action AWS adds to those services later is granted too.
cloudwatch:*logs:*sns:*
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.
