Short explanation

Text::CSV_XS versions before 1.65 for Perl allow record splitting because combine and print do not quote strings used as numbers.

Why does it matter?

This flaw allows a validated numeric value to end a record early and turn subsequent fields into a separate row, causing data integrity issues.

What should be done?

  • Update the software following vendor advisories
  • Use version 1.65 or later
Chain of evidence and sources2 verified claims

Text::CSV_XS sürümleri 1.65 öncesi, combine fonksiyonunda tırnaksız sayı dizgileri nedeniyle kayıt bölmeye izin verir.

Show the technical text from the sources

Text::CSV_XS versions before 1.65 for Perl allow record splitting by writing strings used as numbers without quotes in combine. combine and print do not check whether a field needs quotes when its value has Perl's integer or numeric flag set. Perl sets these flags on a string used in a numeric operation when it parses as a number, which allows leading and trailing whitespace. With binary set, as csv does by default, "12\n" passes a check such as $qty > 0 and is then written unquoted with its newline. A value validated as a number can end the record early and turn the fields after it into a separate row.
