@codemod/secure-param-defaults-audit

Read-only audit of deployment JSON templates for top-level secureString and secureObject parameters that incorrectly include defaultValue, with findings, metrics, and remediation guidance.

What It Does

  • Scans **/*.json deployment templates only.
  • Inspects only the top-level parameters object.
  • Reports one finding per top-level parameter whose type is exactly secureString or secureObject and that also declares defaultValue.
  • Emits file-level metrics for files with findings plus per-type and per-parameter counters.
  • Never rewrites source files.

Detection Rules

The codemod treats a JSON file as a deployment template when it has a top-level parameters object and template markers such as:

  • a deployment template $schema
  • a top-level resources array
  • top-level variables or outputs
  • contentVersion together with typed parameter definitions

Each finding includes stable metadata such as:

  • filePath
  • paramName
  • secureType
  • jsonPointer
  • line and column
  • remediation guidance

Recommended remediation: remove the defaultValue and provide the secret at deployment time through a secure parameter file, a key-management reference, or CI/CD secret injection.

Exclusions

  • non-JSON files
  • non-template JSON documents
  • deployment parameter files that use the deployment-parameters schema
  • nested objects coincidentally named parameters
  • parameter types other than exact secureString and secureObject
  • secure parameters that omit defaultValue
  • defaultValue mentions that only appear in metadata, descriptions, or examples

Metrics

  • deployment_templates_scanned
  • deployment_secure_param_defaultvalue_files
  • deployment_secure_param_defaultvalue_findings
  • deployment_securestring_defaultvalue_findings
  • deployment_secureobject_defaultvalue_findings

Current parser mode uses JSSG's JSON language, so malformed JSON files do not reach the transform. The optional unparsable-file metric from the spec is therefore not emitted by this package.
