CVE-2026-115943

Not yet rated

Not yet rated — under the NVD policy in effect since April 2026, most CVEs are no longer analyzed immediately. The EPSS score (if available) is still shown.

Description

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.
