CVE-2026-115943 is fixed in libspreadsheet-xlsx-perl on 1 platform by DEBIAN-CVE-2026-115943 (version 0.20-1), released November 3, 2026. It is not reported as exploited. Patch Radar priority: Urgent.
Spreadsheet::XLSX versions before 0.19 for Perl allow code execution via string eval of number format conditions in ExcelFmt. When a number format has a condition such as [>100], ExcelFmt chooses the format section by passing the condition and the cell value to a string eval. Both come from the workbook, and the eval runs while Spreadsheet::XLSX->new parses it. An attacker who supplies an XLSX file can run arbitrary Perl code.
