{"cve":"CVE-2026-107211","nvd":{"published":"2026-10-07T18:17:18.490","modified":"2026-10-13T14:24:41.017","status":"Analyzed","description":"Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.1 to 2.11.0, separately parsed pivot-table field indices are used to index the pivot-cache field-name slice without bounds checks. extractPivotTableFields uses getPivotCacheFieldsName output while processing GetPivotTables and trusts the dataField fld attribute as an index. When a crafted workbook supplies a pivot-field count mismatch or an out-of-range dataField fld value before GetPivotTables is called, the unchecked index causes a Go slice-bounds panic that escapes the library, allowing an attacker to crash the process or request worker. No fixed version is available as of this review.","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:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-129"],"references":["https://github.com/qax-os/excelize/commit/6258dcebc4e2a2aed985c38a08098dfd908521d1","https://github.com/qax-os/excelize/pull/2435","https://github.com/qax-os/excelize/security/advisories/GHSA-mx22-3794-2vpv"],"products":["excelize:excelize"],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107211","score":0.00234,"percentile":0.14156,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-mx22-3794-2vpv","url":"https://osv.dev/vulnerability/GHSA-mx22-3794-2vpv","summary":"Excelize: Unchecked pivot-cache field index in extractPivotTableFields causes unrecoverable panic","modified":"2026-10-19T21:41:17.333023394Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":[">=2.8.1 <2.11.1-0.20261003002531-6258dcebc4e2"],"fixed":["2.11.1-0.20261003002531-6258dcebc4e2"]}]},{"id":"GO-2026-6695","url":"https://osv.dev/vulnerability/GO-2026-6695","summary":"Panic via unchecked pivot-cache field index in github.com/xuri/excelize/v2","modified":"2026-10-19T21:31:39.256956036Z","packages":[{"ecosystem":"Go","name":"github.com/xuri/excelize/v2","purl":"pkg:golang/github.com/xuri/excelize/v2","ranges":[">=2.8.1 <2.11.1-0.20261003002531-6258dcebc4e2"],"fixed":["2.11.1-0.20261003002531-6258dcebc4e2"]}]}],"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).
