Go to dashboardExcelize, a Go library for reading and writing Excel files, versions 2.1.0 through 2.11.0 fail to enforce a row-number limit in Rows.Columns, so a crafted worksheet makes GetRows or the Rows iterator loop through every missing row. An attacker who can supply a spreadsheet can tie up a CPU core for as long as they choose.

If the version is 2.1.0 through 2.11.0, or below the listed fix, the module is affected.
2.11.1-0.20260930021559-01a9ff32fb3c, the fixed version listed in the govuln product dataEach row is the first time that source carried this signal. The analyst’s rows are its own findings.
Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.1.0 to 2.11.0, Rows.Columns accepts a look-ahead row number above TotalRows without applying the limit enforced by Rows.Next. File.GetRows relies on Rows.Next and Rows.Columns, but Rows.Columns consumes the row r attribute without the limit check in Rows.Next. When a crafted worksheet places an oversized row number after an ordinary valid row and the application calls GetRows or iterates Rows, the iterator advances through every missing row number instead of rejecting the workbook, allowing an attacker to consume a CPU core for an attacker-controlled duration. No fixed version is available as of this review.
