flowise is vulnerable to Cross-Site Scripting (XSS). The vulnerability is due to insufficient input sanitization in the /api/v1/credentials/id endpoint, which reflects user input back in the 404 page as HTML. This allows attackers to craft a URL that injects JavaScript into user sessions, enabling them to steal information, create false popups, or redirect users to other websites without interaction.
