description

Text::CSV_XS versions before 1.65 can add an unexpected byte to a parsed empty trailing field. An attacker able to supply CSV data may cause this result when an input record ends with a delimiter followed by a standalone carriage return; UTF-8-marked input can also yield malformed text.

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.

fixed in 1.65
