AI-powered analysis for quick understanding

This vulnerability allows an attacker to manipulate the file_format parameter in the OpenChatBI tool, potentially letting them access or overwrite files on the server that they shouldn't be able to reach. It requires the attacker to have access to the tool and to exploit the flaw before the software is updated to version 0.2.2, which fixes the issue.

Technical Description

OpenChatBI is an intelligent chat-based BI tool powered by large language models, designed to help users query, analyze, and visualize data through natural language conversations. Prior to version 0.2.2, the save_report tool in openchatbi/tool/save_report.py suffers from a critical path traversal vulnerability due to insufficient input sanitization of the file_format parameter. This issue has been patched in version 0.2.2.
