CVE-2026-59161 – Excelize: Streaming GetRows row-bound bypass causes attacker-controlled allocation

CVE ID :CVE-2026-59161

Published : July 10, 2026, 5:17 p.m. | 32 minutes ago

Description :Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. Prior to 2.11.0, the streaming worksheet reader used by Rows and GetRows does not enforce the TotalRows limit on the row r attribute, allowing a small XLSX file with a row number above 1048576 and no cell coordinate to make GetRows append empty rows up to the attacker-controlled index and consume excessive memory and CPU. This issue is fixed in version 2.11.0.

Severity: 8.7 | HIGH
