arXiv:2605.19192v1 Announce Type: new Abstract: Multimodal agents use screenshots, documents, and webpages to choose tool calls. 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. We propose evidence-carrying multimodal agents (ECA), which treat free-form model text as inadmissible evidence. ECA decomposes each t
The rapid advancement and deployment of multimodal AI agents are exposing critical vulnerabilities in their permissioning and action-taking mechanisms, necessitating immediate solutions to prevent misuse.
This research addresses a fundamental flaw where AI hallucination can be weaponized into unauthorized actions, transforming a quality control issue into a security and trust problem for autonomous systems.
The proposed 'evidence-carrying multimodal agents' (ECA) paradigm shifts AI agent design from accepting free-form model text as valid input to demanding explicit, verifiable evidence for actions, significantly increasing security and reliability.

Companies will prioritize the implementation of verifiable evidence mechanisms in their AI agent deployments to mitigate risks.
New regulatory frameworks may emerge, mandating auditable evidence chains for autonomous AI actions in sensitive sectors.
A shift in AI development towards 'evidence-first' architectures could transform how AI systems interact with and control critical infrastructure.
