GO-2026-6453 Unbounded memory allocation via streaming row reader in github.com/xuri/excelize

In github.com/xuri/excelize/v2, the streaming worksheet reader used by Rows and GetRows does not enforce the maximum row limit TotalRows on row "r" attributes. A crafted spreadsheet with an out-of-bounds row index causes GetRows to allocate empty row slices up to the specified row number, leading...
