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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-95"],"vendors":[],"products":[],"references":[{"url":"https://metacpan.org/release/ASB/Spreadsheet-XLSX-0.19/changes","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/10/30/3","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
