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 launch resources that run as a more privileged role
Grants the actions of 2 documented escalation paths, but only on named resources or under a condition. Review that scope before trusting it.
- cloudformation-001iam:PassRole + cloudformation:CreateStackscoped
  - iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/aws-elasticbeanstalk-*
  - cloudformation:CreateStack: on arn:aws:cloudformation:*:*:stack/awseb-e-*
- ec2-001iam:PassRole + ec2:RunInstancesscoped
  - iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/aws-elasticbeanstalk-*
  - ec2:RunInstances: condition ec2:LaunchTemplate
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.
Medium
Can take over existing resources that run as another role
Grants the actions of 1 documented escalation path, but only on named resources or under a condition. Review that scope before trusting it.
- cloudformation-002cloudformation:UpdateStackscoped
  - cloudformation:UpdateStack: on arn:aws:cloudformation:*:*:stack/awseb-e-*
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.

Suggestion / REDUNDANT_RESOURCE
The 2 resource ARN(s) are redundant because they reference the same resource. Review the use of wildcards (*), or remove the resource arn:aws:s3:::elasticbeanstalk-env-resources-*/* to remove the redundancy. AWS docs
