Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Excelize (github.com/xuri/excelize/v2) versions 2.8.1 up to but not including 2.11.1-0.20260911060113-ea12859e43c6 are vulnerable. A crafted workbook with two mutually referencing ANCHORARRAY dynamic array formulas causes unbounded recursion during formula evaluation, which ends in a fatal Go stack overflow that aborts the whole process. An attacker only needs to supply such a workbook to an application that evaluates its cells, such as through CalcCellValue, AddPivotTable, or AddPicture. Upgrade to 2.11.1-0.20260911060113-ea12859e43c6 or later. No configuration workaround is listed.
