Unauthenticated agent data disclosure via unguarded export

Published Jun 15, 2026 · Updated Jun 15, 2026

Information disclosure in HKUDS AI-Trader allows remote attackers to download registered-agent records through the Research Export API. The /api/research/agents.csv handler returned the full registered-agent database without authenticating the request or checking the research_exports capability. Network access to a deployed service is sufficient, exposing internal agent IDs and precise financial balances without user interaction.
