CVE-2026-124018

Gutenverse Form plugin for WordPress before 3.2.2 contains a CSV formula injection vulnerability that allows unauthenticated attackers to inject spreadsheet formula-trigger characters by submitting free-text field values to the public form-submit REST route, which sanitizes input with sanitizetextfield() without stripping characters such as =, +, @, or a leading minus. Attackers can store malicious formulas in entry-data post meta that are later exported unneutralized via fputcsv() or eschtml() in the CSV export functions, causing the formula to execute when an administrator opens the exported file, enabling data exfiltration to an attacker-controlled URL or command execution on the administrator's workstation.
