  "summary": "Text::CSV_XS versions before 1.65 can add an unexpected byte to a parsed empty trailing field.

  "mitigation": "Upgrade Text::CSV_XS to version 1.65 or later. Until upgraded, reject or normalize CSV records that end with an empty field followed by a standalone carriage return before parsing.",
