CVE-2026-59161

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. Prior to 2.11.0, the streaming worksheet reader used by Rows and GetRows does not enforce the TotalRows limit on the row r attribute, allowing a small XLSX file with a row number above 1048576 and no cell coordinate to make GetRows append empty rows up to the attacker-controlled index and consume excessive memory and CPU. This issue is fixed in version 2.11.0.

Summary		(es) Excelize es una biblioteca del lenguaje Go para la lectura y escritura de hojas de cálculo de Microsoft Excel. Antes de la versión 2.11.0, el lector de hoja de cálculo en streaming utilizado por Rows y GetRows no aplica el límite de TotalRows en el atributo r de fila, permitiendo que un archivo XLSX pequeño con un número de fila superior a 1048576 y sin coordenadas de celda haga que GetRows añada filas vacías hasta el índice controlado por el atacante y consuma memoria y CPU excesivas. Este problema está solucionado en la versión 2.11.0.
