PublishedExcelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.0.0 to 2.11.0, checkRow sizes its target cell slice from the last cell in XML document order and then re-scatters every cell by its explicit column reference. GetCellValue reaches workSheetReader and checkRow, where targetList is too short for an earlier out-of-order cell. When a crafted row places a higher-column cell before a lower-column final cell and a non-streaming worksheet API reads the sheet, the earlier cell's column index exceeds the slice length derived from the final cell, allowing an attacker to cause an unrecovered panic and terminate the process. No fixed version is available as of this review.
