Both come from the workbook, and the eval runs while Spreadsheet::XLSX->new parses it.\n\nAn attacker who supplies an XLSX file can run arbitrary Perl code.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-95"],"references":["https://metacpan.org/release/ASB/Spreadsheet-XLSX-0.19/changes","http://www.openwall.com/lists/oss-security/2026/10/30/3"],"products":[],"source":"nvd","synced_at":"2026-10-30T02:36:39.373463485+00:00"},"epss":null,"kev":null,"osv":[],"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).
