# Panic via unchecked pivot-cache field index in github.com/xuri/excelize/v2

Excelize, a Go library for reading and writing Excel files, panics on a crafted workbook with a pivot-table field count mismatch or an out-of-range dataField index when GetPivotTables is called. An attacker who can supply a spreadsheet can crash the process or the request worker that parses it.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- go:github.com/xuri/excelize/v2 affected >= 2.8.1, < 2.11.1-0.20261003002531-6258dcebc4e2 fixed 2.11.1-0.20261003002531-6258dcebc4e2

## How to check

Run `go list -m github.com/xuri/excelize/v2` in each service and check whether the version is between 2.8.1 and 2.11.0 inclusive.

## Fix

Move to 2.11.1-0.20261003002531-6258dcebc4e2 as listed by govuln; the description says no fixed version exists yet, so confirm before relying on it. Until then, reject or sandbox untrusted workbooks before calling GetPivotTables.

## From the sources

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.1 to 2.11.0, separately parsed pivot-table field indices are used to index the pivot-cache field-name slice without bounds checks. extractPivotTableFields uses getPivotCacheFieldsName output while processing GetPivotTables and trusts the dataField fld attribute as an index. When a crafted workbook supplies a pivot-field count mismatch or an out-of-range dataField fld value before GetPivotTables is called, the unchecked index causes a Go slice-bounds panic that escapes the library, allowing an attacker to crash the process or request worker. No fixed version is available as of this review.
