CVE-2025-11576Network attack vector

Spreadsheet code execution via unsanitized exported messages

Published Oct 24, 2025 · Updated Oct 24, 2025

CSV injection in NewCodeByte AI Chatbot Free Models 1.6.5 and earlier allows remote attackers to plant formulas in exported messages. The newcodebyte_chatbot_export_messages function writes attacker-controlled chat content to CSV cells without neutralizing formula-leading characters. Execution requires an administrator to export the messages and open the file in spreadsheet software configured to evaluate the formula.
