The Trusted Executor Dilemma: Agents Obey Malicious READMEs

Researchers systematically measured what happens when adversarial instructions are embedded in project documentation that high-privilege agents are directed to read. The result: agents with terminal, filesystem, and network access blindly execute the instructions and exfiltrate data. This isn't a jailbreak — it's the agent doing exactly what it was designed to do (follow instructions) on adversarial input. Builders shipping coding agents or CI/CD agents should audit all documentation sources treated as trusted input.
