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."}], "lastModified": "2026-10-13T13:08:51.830", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:excelize:excelize:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "4FABD6F5-28D2-4CF0-9609-156698F346C1", "versionEndIncluding": "2.11.0", "versionStartIncluding": "2.8.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
