A path traversal vulnerability in the \'/apply_settings\' endpoint of parisneo/lollms-webui allows attackers to execute arbitrary code. The vulnerability arises due to insufficient sanitization of user-supplied input in the configuration settings, specifically within the \'extensions\' parameter. Attackers can exploit this by crafting a payload that includes relative path traversal sequences (\'../../../\'), enabling them to navigate to arbitrary directories. This flaw subsequently allows the server to load and execute a malicious \'__init__.py\' file, leading to remote code execution. The issue affects the latest version of parisneo/lollms-webui.
