Banking AI Agent Vulnerable to XSS via Payment Reference

TL;DR. A banking AI agent demonstrated vulnerabilities to Cross-Site Scripting (XSS) and indirect prompt injection through payment references. - Attackers could compromise user sessions by embedding malicious code in transaction details or PDF documents. - The vulnerability exploits how the AI agent processes and displays user-generated content, leading to unauthorized access. - This highlights risks in AI systems that handle sensitive financial data and interact with external inputs.

• A banking AI agent was found susceptible to Cross-Site Scripting (XSS) and indirect prompt injection.
• The exploit allowed session compromise through malicious payment references or specially crafted PDFs.
• The vulnerability arose from the AI agent's processing of user-controlled data within financial transactions.
• This case demonstrates critical security flaws in AI systems handling sensitive banking information.
• Prompt injection methods enabled attackers to manipulate the AI's behavior and extract data.
• The findings underscore the need for robust input validation and sanitization in AI-powered financial tools.
