From 2.1.0 to 2.11.0, a Zip64 uncompressed size with the high bit set is converted from uint64 to a negative int64 before signed size-limit checks and allocation. ReadZipReader obtains UncompressedSize64 through FileInfo.Size and passes the wrapped negative value to readFile. When a crafted Zip64 entry declares an uncompressed size from 2^63 through 2^64-1 and the workbook is opened, the negative size bypasses unzip limits and reaches make as a negative capacity, allowing an attacker to panic during workbook opening. No fixed version is available as of this review.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD 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":null}],"references":["https://github.com/qax-os/excelize/security/advisories/GHSA-fw94-4wwp-w8pw","https://github.com/qax-os/excelize/pull/2369","https://github.com/qax-os/excelize/commit/db93f8d89de71589069a54d1b998af02e3c5f7cd"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-94555","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 7, 2026, 6:53:27 PM","dateUpdated":"Oct 7, 2026, 7:30:13 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
