{"id":"CVE-2026-110758","summary":"Text::CSV_XS versions before 1.65 for Perl read before the start of an all-blank field under allow_whitespace in strip_trail_whitespace","details":"Text::CSV_XS versions before 1.65 for Perl read before the start of an all-blank field under allow_whitespace in strip_trail_whitespace.\n\nUnder allow_whitespace, strip_trail_whitespace removes trailing spaces and tabs from each unquoted field without stopping at the start of the field. 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.","modified":"2026-10-21T10:45:44.437931278Z","published":"2026-10-16T22:08:10.917Z","database_specific":{"cna_assigner":"CPANSec","cwe_ids":["CWE-127"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110758.json"},"references":[{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110758.json"},{"type":"PACKAGE","url":"https://github.com/cpan-authors/Text-CSV_XS"},{"type":"FIX","url":"https://github.com/cpan-authors/Text-CSV_XS/commit/efed7ee21177c59a5b69e787f84154e1fcb0d095.patch"},{"type":"ADVISORY","url":"https://metacpan.org/release/HMBRAND/Text-CSV_XS-1.65/changes"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110758"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cpan-authors/text-csv_xs","events":[{"introduced":"0"},{"fixed":"84085bcda35b916ff251e433cc5b7a1cf04066f5"},{"fixed":"efed7ee21177c59a5b69e787f84154e1fcb0d095"}],"database_specific":{"extracted_events":[{"strategy":"StandardRange","range":[{"introduced":"0"},{"fixed":"1.65"}],"source":"AFFECTED_FIELD"},{"range":[{"fixed":"efed7ee21177c59a5b69e787f84154e1fcb0d095"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["1.64","1.63","1.62","1.61","1.60","1.59","1.58","1.56","1.55","1.54","1.53","1.51","1.50","1.49","1.48","1.47","1.46","1.45","1.44","1.43","1.42","1.41","1.40","1.39","1.38","1.37","1.36","1.35","1.34","1.33","1.32","1.31","1.30","1.29","1.28","1.27","1.26","1.25","1.24","1.23","1.22","1.21","1.20","1.19","1.18","1.17","1.16","1.15","1.14","1.13","1.12","1.11","1.10","1.09","1.08","1.07","1.06","1.05","1.04","1.03","1.02","1.01","1.00","0.99","0.98","0.97","0.96","0.95","0.94","0.93","0.92","0.91","0.90","0.88","0.87","0.86","0.85","0.84","0.83","0.82","0.81","0.80","0.79","0.78","0.77","0.76","0.75","0.74","0.73","0.72","0.71","0.70","0.69","0.68","0.67","0.66","0.65","0.64","0.63","0.62","0.61","0.60","0.59","0.58","0.57","0.56","0.55","0.54","0.53","0.52","0.51","0.50","0.46","0.45","0.44","0.43","0.42","0.41","0.40","0.37","0.36","0.35-Valloire","0.34","0.33"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110758.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
