For a field of only blanks it reads the byte before the field's heap buffer. If that byte is also a space or tab, it may be zeroed and the walk continue backwards, depending on what the allocator placed there.\n\nLeading blanks are normally skipped before a field is stored, but an all-blank field still arrives after a leading escape_char that differs from quote_char, or as a quoted field in getline when its line ends in two CRs.","state":0,"publishedAt":"2026-10-16T22:08:10.917+00:00","modifiedAt":"2026-10-20T18:31:16.823+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\": \"strip_trail_whitespace\"\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/efed7ee21177c59a5b69e787f84154e1fcb0d095.patch","https://metacpan.org/release/HMBRAND/Text-CSV_XS-1.65/changes"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110758","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110758","identifiers":["CVE-2026-110758"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
