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 take over existing resources that run as another role
Grants every action of 1 documented escalation path on any resource with no condition.
- ssm-002ssm:SendCommandunrestricted
Use with caution: List the roles attached to the functions, instances, pipelines or notebooks it can modify: the holder effectively has them too.
High
Can read secrets
Reads Parameter Store values, SecureString included where the KMS key allows it, on any resource with no condition.
ssm:GetParameters
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.
