A developer describes a prompt injection vulnerability in their AI job-matching side project, Upwork Scout. The issue arises because the language model, Claude Haiku, cannot reliably distinguish between the developer's instructions and content provided by a stranger within the job post. While the potential damage is limited due to strict output formatting and access controls, the developer emphasizes that the model's output should always be treated as untrusted user input, necessitating robust input sanitization and access management within the application.
