At a glance

CVE-2025-11576 is a medium-severity Improper Neutralization of Formula Elements in a CSV File vulnerability in the AI Chatbot Free Models WordPress plugin, affecting versions <= 1.6.5. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.6.6; sites on affected versions should update now. Disclosed October 2025, reported by Jonas Benjamin Friedli.

Vulnerability Overview

The AI Chatbot Free Models – Customer Support, Live Chat, Virtual Assistant plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 1.6.5. This is due to insufficient sanitization in the 'newcodebyte_chatbot_export_messages' function. This makes it possible for unauthenticated attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

CWE-1236: Improper Neutralization of Formula Elements in a CSV File

The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.

Remediation

Update to version 1.6.6, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: AI Chatbot Free Models 1.6.6 closes this, and updating the plugin is the step that ends it.
