LOW
The severity is rated as LOW because this scenario describes a best practice approach rather than an exploitable vulnerability. However, the implementation must be carefully managed to ensure that no security gaps are created during transition.

The content discusses the transition of a new hire into an organization where they plan to import all cloud resources to Infrastructure as Code (IaC) using Terraform. The focus is on managing PostgreSQL and Keycloak through Ansible, aiming to reduce developer permissions and enforce changes via PRs. This approach helps in maintaining security by ensuring that only authorized configurations are deployed after review. By centralizing the management of databases and users within code repositories, the organization can achieve better control over infrastructure state and minimize risks associated with direct access to production environments.

Affected Systems
  • PostgreSQL (all versions)
  • Keycloak (all versions)
Remediation
  • Ensure all PostgreSQL and Keycloak configurations are version-controlled using Ansible playbooks. Example: `ansible-playbook -i inventory.yml postgresql-config.yml`
  • Implement PR-based workflow for changes to infrastructure code. Use tools like GitHub Actions or GitLab CI/CD pipelines.
  • Reduce developer permissions in both PostgreSQL and Keycloak to only those needed through the IaC configurations.
Stack Impact

Minimal direct impact as this is more about best practices rather than a specific vulnerability. However, it affects common homelab stacks by improving security postures around database and identity management.
