{"cve":"CVE-2026-107217","nvd":{"published":"2026-10-07T19:17:33.957","modified":"2026-10-13T14:23:36.643","status":"Analyzed","description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.0.0 to 2.11.0 in github.com/xuri/excelize/v2 and from 1.1.0 to 1.4.1 in github.com/xuri/excelize, ColumnNameToNumber accumulates a bijective base-26 value in int64 without detecting overflow, allowing an invalid long column name to wrap to zero with no error. ColumnNameToNumber accepts the overflowing name VGWQHXLSDVIKWV, after which checkSheetR0 and xlsxWorksheet.checkRow use the wrapped column value as an index. When a crafted worksheet uses an overflowing column name in a row normalized by checkSheetR0 or checkRow, the wrapped zero column becomes a negative slice index during worksheet normalization, allowing an attacker to panic and terminate the calling process. No fixed version is available as of this review.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-129","CWE-190"],"references":["https://github.com/qax-os/excelize/commit/696050fbf14e74e96a58eef2b16aaf72f381a6a8","https://github.com/qax-os/excelize/pull/2394","https://github.com/qax-os/excelize/security/advisories/GHSA-c85p-xxjj-2r75","https://github.com/qax-os/excelize/security/advisories/GHSA-c85p-xxjj-2r75"],"products":["excelize:excelize"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107217","score":0.00363,"percentile":0.29814,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-c85p-xxjj-2r75","url":"https://osv.dev/vulnerability/GHSA-c85p-xxjj-2r75","summary":"Excelize ColumnNameToNumber: int64 overflow yields an out-of-domain coordinate with nil error, causing negative slice index panic on r=\"0\" rows","modified":"2026-10-07T20:30:05.831565732Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":[">=2.0.0 <2.11.1-0.20260910071107-696050fbf14e"],"fixed":["2.11.1-0.20260910071107-696050fbf14e"]},{"ecosystem":"Go","name":"github.com/xuri/excelize","purl":"pkg:golang/github.com/xuri/excelize","ranges":[">=1.1.0 <=1.4.1"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
