{"cve":"CVE-2026-107212","nvd":{"published":"2026-10-07T18:17:18.670","modified":"2026-10-13T14:24:29.523","status":"Analyzed","description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.1.0 to 2.11.0, Rows.Columns accepts a look-ahead row number above TotalRows without applying the limit enforced by Rows.Next. File.GetRows relies on Rows.Next and Rows.Columns, but Rows.Columns consumes the row r attribute without the limit check in Rows.Next. When a crafted worksheet places an oversized row number after an ordinary valid row and the application calls GetRows or iterates Rows, the iterator advances through every missing row number instead of rejecting the workbook, allowing an attacker to consume a CPU core for an attacker-controlled duration. 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:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/qax-os/excelize/commit/01a9ff32fb3c1f873cf01205e1b8a3285b0e1d23","https://github.com/qax-os/excelize/pull/2438","https://github.com/qax-os/excelize/security/advisories/GHSA-jw42-f3rr-4cc3"],"products":["excelize:excelize"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107212","score":0.00363,"percentile":0.29814,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jw42-f3rr-4cc3","url":"https://osv.dev/vulnerability/GHSA-jw42-f3rr-4cc3","summary":"Excelize: Unbounded row number in Rows.Columns makes GetRows and the Rows iterator loop for days","modified":"2026-10-19T21:40:42.350043538Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":[">=2.1.0 <2.11.1-0.20260930021559-01a9ff32fb3c"],"fixed":["2.11.1-0.20260930021559-01a9ff32fb3c"]}]},{"id":"GO-2026-6685","url":"https://osv.dev/vulnerability/GO-2026-6685","summary":"Excelize: Unbounded row number in Rows.Columns makes GetRows and the Rows iterator loop for days in github.com/xuri/excelize","modified":"2026-10-19T21:31:35.411648040Z","packages":[{"ecosystem":"Go","name":"github.com/360EntSecGroup-Skylar/excelize/v2","purl":"pkg:golang/github.com/360EntSecGroup-Skylar/excelize/v2","ranges":[">=2.1.0"],"fixed":[]},{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":["<2.11.1-0.20260930021559-01a9ff32fb3c"],"fixed":["2.11.1-0.20260930021559-01a9ff32fb3c"]}]}],"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).
