CVE-2026-107212 - Excelize: Unbounded row number in Rows.Columns makes GetRows and the Rows iterator loop for days
CVE ID :CVE-2026-107212
Published : Oct. 7, 2026, 5:29 p.m. | 16 minutes ago
Description :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.
Severity: 0.0 | NA
