From 2.1.0 to 2.11.0, flatCols expands file-loaded column ranges without validating Min and Max against the worksheet column limit. SetColWidth reaches flatCols, which expands xlsxCol.Min through xlsxCol.Max without enforcing MaxColumns. When a crafted worksheet supplies an oversized col max attribute and the application invokes a column mutator, flatCols performs a deep copy and append for every attacker-selected column number, allowing an attacker to consume excessive CPU and memory or trigger OOM. No fixed version is available as of this review.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":null}],"references":["https://github.com/qax-os/excelize/security/advisories/GHSA-fq3v-74gv-27gm","https://github.com/qax-os/excelize/pull/2370","https://github.com/qax-os/excelize/commit/a54c578af309fa81f448143ed2b7a91192cc58a7"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-94554","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 7, 2026, 6:48:54 PM","dateUpdated":"Oct 7, 2026, 10:05:27 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
