In-the-Wild Attack Abuses AI Agents' Trust in Markdown

Researchers discovered a prompt injection attack that exploits how artificial intelligence (AI) agents interpret local instruction files, treating text documents as executable commands. The technique leverages the trust AI coding assistants place in markdown formatting to manipulate behavior. This attack demonstrates a vulnerability in how AI systems handle local file consumption without strict boundaries between data and instructions.

Why it matters: Development teams using AI coding assistants face immediate risk of prompt injection attacks that could alter code generation, introduce malicious logic, or exfiltrate sensitive information from local files through trusted markdown interpretation.
