  "title": "Quadratic CPU consumption in Text::CSV_XS CSV parsing",
  "summary": "Text::CSV_XS versions before 1.65 can consume disproportionate CPU while parsing CSV input with carriage-return-only line endings. An attacker able to supply CSV to an application using getline with the default end-of-line configuration can cause processing delays or resource exhaustion.",
  "mitigation": "Upgrade Text::CSV_XS to version 1.65 or later. Until upgrading, reject or normalize carriage-return-only CSV input and configure CSV line-ending handling explicitly.",
