CVE-2026-110759— Text::CSV_XS versions before 1.65 for Perl return a 0xFF byte that is not in the input for an empty last field followed by a lone CR in parse

Quick assessment

Affected
CVE-2026-110759
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Perl 的 Text::CSV_XS 模块在 1.65 版本之前存在一个漏洞：当解析（parse）操作的输入以“分隔符后跟一个单独的 CR（回车符）”结尾，且最后一个字段为空时，解析器会返回一个输入中并不存在的 0xFF 字节。 具体表现为：当输入以分隔符和单独的 CR 结尾时，解析器会将输入末尾视为下一个字符，并将文件结束标记（EOF marker）以字节 0xFF 的形式存入该字段。若启用了二进制模式，调用 会返回两个字段："a" 和 "\xFF"。如果输入被标记为 UTF-8，则最后一个字段会成为包含该单字

Vulnerability Title
Text::CSV_XS versions before 1.65 for Perl return a 0xFF byte that is not in the input for an empty last field followed by a lone CR in parse
Source: CVE Program / CVE List V5
Vulnerability Description
Text::CSV_XS versions before 1.65 for Perl return a 0xFF byte that is not in the input for an empty last field followed by a lone CR in parse. When the input to parse ends in a separator and a lone CR, the parser treats the end of the input as the next character and stores the end-of-file marker in the field as the byte 0xFF. With binary set, parse("a,\r") returns the fields "a" and "\xFF". On UTF-8 flagged input the last field is a UTF-8 flagged string holding that lone byte, which is malformed UTF-8. The same input with a non-empty last field is rejected as an error. A CRLF file read line by line and chomped ends this way when its last column is empty, so the application receives a byte that is not in its input.
