CVE-2026-59162

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. Prior to 2.11.0, Excelize parses shared-string cell values with strconv.Atoi and checks only the upper bound before indexing the shared string slice, allowing an XLSX file containing a shared-string cell with -1 to trigger sharedStrings[-1] and panic when read through GetCellValue or GetRows. This issue is fixed in version 2.11.0.

Summary		(es) Excelize es una biblioteca del lenguaje Go para leer y escribir hojas de cálculo de Microsoft Excel. Antes de la versión 2.11.0, Excelize analiza los valores de celda de cadena compartida con strconv.Atoi y verifica solo el límite superior antes de indexar la porción de cadena compartida, lo que permite que un archivo XLSX que contiene una celda de cadena compartida con -1 active sharedStrings[-1] y cause un pánico cuando se lee a través de GetCellValue o GetRows. Este problema se solucionó en la versión 2.11.0.
