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.","state":0,"publishedAt":"2026-10-07T18:55:55.603+00:00","modifiedAt":"2026-10-10T02:42:21.546+00:00","affected":[{"ecosystem":"Vendor product","name":"excelize","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"qax-os\",\n                    \"product\": \"excelize\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.8.0, <= 2.11.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/qax-os/excelize/security/advisories/GHSA-5h23-36rv-pm65","https://github.com/qax-os/excelize/pull/2367","https://github.com/qax-os/excelize/commit/ae2113b410e51f6a141c396a59eda8c42b91bc22"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107225","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107225","identifiers":["CVE-2026-107225"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
