Summary

• Move the SSH ingress CIDR in asg.tf to a new required variable, admin_ssh_cidr. Set it in terraform.tfvars, which git ignores, so the admin IP is not in git.
• Add an admin_ssh_cidr output.

Notes

• The variable has no default. Anyone who runs Terraform must set it in their own terraform.tfvars.

low bug, confidence medium, pass review

No validation of CIDR format in required variable

The variable is a bare string with no validation block. An empty or malformed value (for example an unset tfvars entry set to an empty string) will only fail at apply time inside the AWS API, or could yield an unintended rule. A validation using cidrhost or can(cidrnetmask) would catch this at plan time.

No validation on SSH CIDR variable

admin_ssh_cidr accepts any string and feeds the security group SSH ingress rule. An operator could set 0.0.0.0/0 by mistake, which would expose SSH to the internet. The input comes from the operator's tfvars, so the impact is limited, but a validation block could reject overly broad ranges. The old value was a fixed /32.

Pass	Status	Model	Summary
Review	✅ ok	claude-sonnet-5-5	The PR moves the hardcoded SSH ingress CIDR into a required variable `admin_ssh_cidr` with a /32 IPv4 validation, and adds an output for it. One issue: the module's `cidr_blocks` field expects a comma-separated string, so a single /32 string works. The validation looks correct. No clear bugs found.
Security	✅ ok	claude-sonnet-5-5	The PR moves a hard-coded SSH ingress CIDR into a required, validated variable (/32 only) and adds an output that exposes it. The validation reduces risk of opening SSH broadly. The one concern is that the new output prints the admin IP, which the PR says it wants kept out of git.
Supply chain	✅ ok	claude-sonnet-5-5	The PR moves a hardcoded SSH ingress CIDR in the ECS autoscaling security group to a new required variable `admin_ssh_cidr` with a /32 validation, and adds an output for it. No dependency changes, no CI or workflow edits, no network calls, no obfuscation, and no text aimed at an AI reviewer. The change narrows nothing and widens nothing beyond requiring the value be a single IPv4 /32. I found no supply-chain or malicious concerns.

Admin IP exposed via Terraform output

The output prints the admin SSH CIDR to the CLI, to CI logs and to remote state readers. This partly defeats the goal of keeping the admin IP out of public view. The exposure is minor, since the value is a single allowlisted IP and not a credential. An attacker would need access to the logs or the state.
