Risk
MediumThe 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 take over existing resources that run as another role
Grants the actions of 2 documented escalation paths, but only on named resources or under a condition. Review that scope before trusting it.
- ssm:StartSession: on arn:aws:ssm:*:*:document/SSM-SessionManagerRunShell
- ssm:SendCommand: condition aws:CalledViaFirst, on arn:aws:ssm:*:*:document/AWSSSO-CreateSSOUser
Use with caution: Check which roles, users or policies fall inside the scope shown above. Within it the escalation works as documented, so keep privileged principals out of it.
