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 5 permissions management actions across 1 service (s3-outposts) on any resource, enough to share resources outside the account.

    s3-outposts:deleteaccesspointpolicys3-outposts:deletebucketpolicys3-outposts:putaccesspointpolicys3-outposts:putbucketpolicys3-outposts:putobjectacl

    Use with caution: Turn on IAM Access Analyzer external access findings, and keep account-level guards like S3 Block Public Access enabled.

  • Medium

    Full s3-outposts access on every resource

    Uses s3-outposts:* with Resource "*" and no condition, so every action AWS adds to that service later is granted too.

    s3-outposts:*

    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.
