gcloud-sql-user-options: User Options Flag Enabled in Google Cloud SQL Server Instances

id: gcloud-sql-user-options

info:
  name: User Options Flag Enabled in Google Cloud SQL Server Instances
  author: princechaddha
  severity: medium
  description: |
    Checks if the "user options" database flag is configured for Google Cloud SQL Server instances, which can define global defaults for all database users.
  impact: |
    Configuring the "user options" database flag can lead to unintended global defaults for all database users, potentially causing performance issues or undesired behavior.
  remediation: |
    Disable the "user options" database flag for your Google Cloud SQL Server instances to avoid global defaults for all database users.
