{"id":"CVE-2026-110759","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-110759","generatedAt":"2026-10-28T04:37:40.646Z","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.","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.\n\nWhen 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.\n\nA 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.","published":"2026-10-16T23:17:01.000Z","lastModified":"2026-10-20T19:17:30.000Z","status":"Awaiting Analysis","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-1286"],"affected":[],"epss":{"score":0.00407,"percentile":0.34793,"date":"2026-10-27","history":[{"date":"2026-10-17","score":0.00192,"percentile":0.08263}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.41%).
