Hallucination as Exploit: Evidence-Carrying Multimodal Agents
The paper discusses the concept of hallucination in multimodal agents, where false visual claims can lead to unauthorized actions. It introduces evidence-carrying multimodal agents (ECA) that utilize external evidence to validate actions proposed by model language. The study demonstrates that ECA significantly reduces the risk of unsafe actions compared to naive agents.
- ▪Multimodal agents can trigger actions based on false visual claims, leading to authorization failures.
- ▪Evidence-carrying multimodal agents (ECA) treat model text as inadmissible evidence and require external validation for actions.
- ▪The architecture of ECA reduces gate bypass from 15% to 1.3% through targeted hardening steps.

When a false visual claim triggers a click, email, extraction, or transfer, hallucination becomes an authorization failure rather than an answer-quality error. We formalize this failure mode as hallucination-to-action conversion: an unsupported perceptual claim supplies the precondition that makes a privileged action appear permitted.
