Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Excelize (github.com/xuri/excelize/v2) versions from 2.0.0 before 2.11.1-0.20260816084418-46a5eb289448 are affected. A specially crafted worksheet in an XLSX file, where a row's cells are out of column order and an earlier cell references a higher column than the last cell, causes an index-out-of-range panic when the file is read through most non-streaming worksheet APIs, crashing the process. An attacker only needs to get an untrusted spreadsheet opened by the application; no authentication is required. Upgrade to 2.11.1-0.20260816084418-46a5eb289448 or later.
