Machine-written summary

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

GHSA-5h23-36rv-pm65 affects github.com/xuri/excelize/v2 versions from 2.8.0 up to 2.11.1-0.20260731010303-ae2113b410e5. A crafted .xlsx file with a negative fillId, borderId or fontId in its styles can make GetStyle panic on an out-of-range index, crashing any process that reads cell styling from an untrusted workbook. The source describes availability impact only. Upgrade to 2.11.1-0.20260731010303-ae2113b410e5, where this is fixed.
