CVE-2026-85030 Details
Description
A vulnerability has been found in HKUDS AI-Trader up to d03ff6c056b32ced735adf7c19ed8175adb1c8df. The affected element is an unknown function of the file service/server/routes_agent.py of the component selfRegister API Endpoint. Such manipulation of the argument initial_balance leads to business logic errors. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is described as difficult. The exploit has been disclosed to the public and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. profit_percent_for_display() divides by INITIAL_CAPITAL + deposited, and challenge scoring's return_pct also normalises against the attacker-inflated starting_cash. So an inflated initial_balance does not yield artificial percent returns - it inflates the absolute cash/equity column only, which is a cosmetic/leaderboard-gaming concern in a simulated game.
A critical business logic vulnerability has been identified in HKUDS AI-Trader versions prior to d03ff6c056b32ced735adf7c19ed8175adb1c8df. The issue arises in the selfRegister API endpoint, where users can manipulate the initial_balance parameter without any server-side validation or authorization checks. This flaw allows users to create accounts with excessively high balances, potentially leading to an economic collapse within the trading simulation and unauthorized access to premium trading features.
The recommended remediation is to remove the 'initial_balance' parameter from user control and enforce starting balances through backend configuration. If custom balances are necessary for testing, implement strict server-side validation with maximum limits. Additionally, ensure that the selfRegister endpoint cannot manipulate privileged balances associated with administrative accounts.
