CVE-2026-47705: CWE-1236: Improper Neutralization of Formula Elements in a CSV File in baptisteArno typebot.io
TypeBot is a chatbot builder tool. Version 3.16.1 has a CSV injection vulnerability in the result export functionality. The application does not sanitize or escape user-supplied input when generating CSV files. An attacker can inject spreadsheet formulas into input fields, which are later executed when an administrator opens the exported CSV in spreadsheet software such as Microsoft Excel or LibreOffice Calc. Version 3.17.0 patches the issue.
AI Analysis
Technical Summary
TypeBot.io version 3.16.1 is affected by a CSV injection vulnerability (CWE-1236) in the result export feature. User-supplied input is not properly neutralized or escaped when generating CSV files, enabling injection of malicious spreadsheet formulas. When these CSV files are opened in spreadsheet applications, the formulas execute, potentially leading to code execution or data manipulation. This vulnerability has a CVSS 3.1 score of 9.6, indicating critical severity. The vulnerability is fixed in version 3.17.0.
Potential Impact
An attacker can inject malicious spreadsheet formulas into CSV exports that execute upon opening the file in spreadsheet software. This can lead to unauthorized code execution, data manipulation, or other harmful effects impacting confidentiality, integrity, and availability of data handled by administrators using the exported CSV files.
Mitigation Recommendations
Upgrade TypeBot to version 3.17.0 or later, where this CSV injection vulnerability is patched. Until the upgrade is applied, avoid opening CSV exports from untrusted or unsanitized sources in spreadsheet software that executes formulas.
