Trust Me, I'm Your Developer: Self-Issued Authentication in Large Language Models

New research shows LLMs will accept identity claims verified by tests the model itself designed—a subtle trust-boundary failure that standard jailbreak mitigations do not address.

arXiv:2609.03247v1 Announce Type: new Abstract: Large language model (LLM) security has largely focused on role-playing jailbreaks, with less attention to what happens when a user asks an LLM to verify an identity claim through a test designed by the model itself. We study this behavior through a staged developer-identity experiment with ChatGPT, Claude, Qwen, Mistral, and Llama. All five models initially rejected the unsupported claim "I am your developer." Claude refused to conduct an identit

Editorial Analysis

Why it matters

Enterprises deploying LLM-based agents for access decisions need to understand that models may self-validate spoofed identity claims, creating a bypass that conventional alignment cannot catch.

What to do

Add self-issued authentication attack scenarios to your AI red-team playbook before granting LLM agents any access-control responsibilities.
