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.\n\n## Affected\n\n- `Text-CSV_XS < 1.65`\n\n## Remediation\n\nUpgrade to Text-CSV_XS 1.65 or later.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
