{"cve":"CVE-2026-107225","nvd":{"published":"2026-10-07T19:17:35.333","modified":"2026-10-13T13:08:51.830","status":"Analyzed","description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.0 to 2.11.0, GetStyle's fill, border, and font extraction predicates check only upper bounds for attacker-controlled style-table indices. File.GetStyle relies on extractStyleCondFuncs predicates that allow negative FillID, BorderID, and FontID values to reach slice indexing. When a crafted styles.xml supplies a negative fillId, borderId, or fontId and the application reads the style, a negative identifier passes the upper-bound-only predicate and becomes a negative slice index, allowing an attacker to panic while reading cell styling. 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-20","CWE-129"],"references":["https://github.com/qax-os/excelize/commit/ae2113b410e51f6a141c396a59eda8c42b91bc22","https://github.com/qax-os/excelize/pull/2367","https://github.com/qax-os/excelize/security/advisories/GHSA-5h23-36rv-pm65","https://github.com/qax-os/excelize/security/advisories/GHSA-5h23-36rv-pm65"],"products":["excelize:excelize"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107225","score":0.0027,"percentile":0.18979,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5h23-36rv-pm65","url":"https://osv.dev/vulnerability/GHSA-5h23-36rv-pm65","summary":"Excelize: GetStyle panics on a negative fillId, borderId or fontId in styles.xml","modified":"2026-10-07T20:30:06.927051800Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":[">=2.8.0 <2.11.1-0.20260731010303-ae2113b410e5"],"fixed":["2.11.1-0.20260731010303-ae2113b410e5"]}]}],"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).
