DescriptionCVE.org

A Local File Inclusion (LFI) vulnerability exists in the gaizhenbiao/chuanhuchatgpt application, specifically within the functionality for uploading chat history. The vulnerability arises due to improper input validation when handling file paths during the chat history upload process. An attacker can exploit this vulnerability by intercepting requests and manipulating the 'name' parameter to specify arbitrary file paths.
