After each record the parser copies the whole unparsed remainder into a new buffer, which the next call parses and copies again, so the work grows with the square of the input size.\n\nA reader with default options that is sent CSV with classic Mac line endings spends seconds of CPU time on a megabyte of input.","state":0,"publishedAt":"2026-10-16T22:07:10.643+00:00","modifiedAt":"2026-10-20T18:25:20.728+00:00","affected":[{"ecosystem":"https://cpan.org/modules","name":"Text-CSV_XS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"collectionURL\": \"https://cpan.org/modules\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"modules\": [\n                        \"Text::CSV_XS\"\n                    ],\n                    \"packageName\": \"Text-CSV_XS\",\n                    \"packageURL\": \"pkg:cpan/Text-CSV_XS\",\n                    \"programFiles\": [\n                        \"CSV_XS.xs\"\n                    ],\n                    \"programRoutines\": [\n                        {\n                            \"name\": \"Text::CSV_XS::getline\"\n                        }\n                    ],\n                    \"repo\": \"https://github.com/cpan-authors/Text-CSV_XS\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"1.65\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/cpan-authors/Text-CSV_XS/commit/f25e00aacd6fc15857b22487cb2e5ca263f377e0.patch","https://metacpan.org/release/HMBRAND/Text-CSV_XS-1.65/changes"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110755","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110755","identifiers":["CVE-2026-110755"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
