CVE-2026-59161 is a denial-of-service vulnerability in the Excelize Go spreadsheet library before version 2.11.0. The streaming worksheet reader used by the Rows and GetRows APIs fails to enforce the worksheet TotalRows maximum on a row element's r attribute. A crafted XLSX worksheet can specify a row number exceeding Excel's maximum of 1,048,576 while omitting a cell coordinate. GetRows may then append empty rows until reaching the attacker-controlled row index, causing disproportionate allocation and processing.

An availability vulnerability in Excelize's streaming Rows/GetRows parser. An attacker-controlled XLSX row index bypasses Excelize's maximum-row validation, causing CPU and memory allocation proportional to the supplied row number.
A high-severity denial-of-service/resource-exhaustion vulnerability in the Excelize Go spreadsheet library. Crafted XLSX input can cause excessive memory and CPU consumption through an attacker-controlled row index.
A denial-of-service vulnerability in the Excelize Go library where malformed XLSX input can trigger excessive memory and CPU consumption because the streaming worksheet reader does not enforce the TotalRows limit on the row attribute.
