The vulnerability lies within the \u003ccode\u003ecreate_app\u003c/code\u003e function of the \u003ccode\u003ebackend/app/__init__.py\u003c/code\u003e file, which manages the REST API Endpoint. A remote attacker can exploit this flaw by manipulating specific parameters within API requests, effectively bypassing authentication mechanisms. This allows unauthorized access to sensitive functionalities and data. Public exploits are available, increasing the risk of widespread exploitation.
