  Can we introduce some kind of convention for the filename to avoid path traversal?

  Idea 1: Keep the filenames in a constant and always check against it.

  SCHEMAS = {
    "build_report_result_data": "build_report_result_data.json" # we could also include the full path to support EE schemas at some point.
  }
  
  # ....
  
  Rails.root.join('app', 'validators', 'json_schemas', "#{SCHEMAS.fetch(options[:filename])}").to_s
  

  Idea 2: filename should match the regex [a-z0-9-]

  @iamricecake @morefice Can we open additional MR that uses the same json schema validation for Daily Build Report?
