Machine-written summary

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

Excelize (github.com/xuri/excelize/v2) versions 2.7.1 up to 2.11.1-0.20260820023833-99903a3240e5 are affected. A workbook containing a merge cell with an empty ref attribute causes a panic when any non-streaming cell API reads a cell, such as GetCellValue, and the panic crashes the process unless the caller recovers from it. An attacker needs only to get an untrusted .xlsx file opened by the consuming application; no options or special configuration are involved. Upgrade to 2.11.1-0.20260820023833-99903a3240e5 or later.
