Summary

CVE-2026-47705 is a critical-severity Improper Neutralization of Formula Elements in a CSV File (CWE-1236) vulnerability. Its CVSS base score is 9.6 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique User Execution (T1204); ranked at the 31th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-15 (Information Output Filtering) — see the control section below for these in your framework.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

SI-15 Information Output Filtering good match

Output filtering/validation directly stops unneutralized formula elements from being written into CSV files.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require output neutralization for untrusted CSV content to block formula injection.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect formula injection but does not itself implement the mitigation.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and output encoding that directly prevents formula injection in CSV exports.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules for safe CSV generation and handling of untrusted data.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles encourage safe data export design but do not specifically address CSV formula neutralization.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly require neutralization of special characters when writing CSV files.
