{"cve":"CVE-2026-107220","nvd":{"published":"2026-10-07T19:17:34.447","modified":"2026-10-13T14:23:03.713","status":"Analyzed","description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.7.1 to 2.11.0, mergeCellsParser leaves the cached rectangle empty for an empty mergeCell ref and then passes that empty slice to cellInRange without a length check. GetCellValue reaches mergeCellsParser, which passes an empty rectangle derived from the mergeCell ref attribute into cellInRange. When a crafted worksheet contains an empty mergeCell ref and a non-streaming cell API reads the worksheet, cellInRange indexes four positions in an empty slice, allowing an attacker to panic on the first affected cell operation. 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:R/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-125","CWE-129"],"references":["https://github.com/qax-os/excelize/commit/99903a3240e58a47ff28fb8e05a03bd9d496ec24","https://github.com/qax-os/excelize/pull/2379","https://github.com/qax-os/excelize/security/advisories/GHSA-g27h-8qhm-6pff","https://github.com/qax-os/excelize/security/advisories/GHSA-g27h-8qhm-6pff"],"products":["excelize:excelize"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107220","score":0.00264,"percentile":0.18165,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-g27h-8qhm-6pff","url":"https://osv.dev/vulnerability/GHSA-g27h-8qhm-6pff","summary":"Excelize: Panic in cellInRange on a worksheet with an empty mergeCell ref","modified":"2026-10-07T20:30:07.235710736Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":[">=2.7.1 <2.11.1-0.20260820023833-99903a3240e5"],"fixed":["2.11.1-0.20260820023833-99903a3240e5"]}]}],"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).
