Description
SimpleXLSX is software for parsing and retrieving data from Excel XLSx files. Starting in version 1.0.12 and prior to version 1.1.12, when calling the extended toHTMLEx method, it is possible to execute arbitrary JavaScript code. Version 1.1.12 fixes the issue. As a workaround, don't use direct publication via toHTMLEx.
