One Word Opens the Gate: The Option-Channel Attack on Typed Decision Models as Agent GuardrailsSurprising resultPreprint8/10 suggested
What it's about
Many agent architectures use typed decision models (systems that choose from fixed options without generating text) as safety guardrails. The authors tested seven models against adversarial prompts and benign server logs. Inserting harmless log text or misleading option names bypassed safety filters in over sixty percent of tests.
Why it may matter
Standard classification guardrails can easily fail, allowing unauthorized tools to execute inside company systems.
