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.
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.
