Prior to 2.11.0, the streaming worksheet reader used by Rows and GetRows does not enforce the TotalRows limit on the row r attribute, allowing a small XLSX file with a row number above 1048576 and no cell coordinate to make GetRows append empty rows up to the attacker-controlled index and consume excessive memory and CPU. This issue is fixed in version 2.11.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7},"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-400","CWE-770"],"references":["https://github.com/qax-os/excelize/commit/93f0b3caed37f21ef5079e3259c6c21dcfe68453","https://github.com/qax-os/excelize/pull/2331","https://github.com/qax-os/excelize/releases/tag/v2.11.0","https://github.com/qax-os/excelize/security/advisories/GHSA-q5j5-6p94-4gwc","https://github.com/qax-os/excelize/security/advisories/GHSA-q5j5-6p94-4gwc"],"products":["excelize:excelize"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-59161","score":0.00655,"percentile":0.51075,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-q5j5-6p94-4gwc","url":"https://osv.dev/vulnerability/GHSA-q5j5-6p94-4gwc","summary":"Excelize: Streaming GetRows row-bound bypass causes attacker-controlled allocation","modified":"2026-09-17T17:40:35.025451509Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":["<2.11.0"],"fixed":["2.11.0"]},{"ecosystem":"Go","name":"github.com/xuri/excelize","purl":"pkg:golang/github.com/xuri/excelize","ranges":["<=1.4.0"],"fixed":[]}]},{"id":"GO-2026-6453","url":"https://osv.dev/vulnerability/GO-2026-6453","summary":"Unbounded memory allocation via streaming row reader in github.com/xuri/excelize","modified":"2026-09-17T17:30:11.249324252Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":["<2.11.0"],"fixed":["2.11.0"]}]}],"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).
