Jailbreaking Large Language Models with Morality Attacks

Conference: ACL 2026 arXiv: 2604.17053 Code: GitHub Area: AI Safety / Moral Robustness Keywords: morality attack, jailbreak attack, value pluralism, LLM robustness, moral judgment

TL;DR

This paper constructs a 10.3K morality attack dataset (covering value ambiguity and value conflict scenarios) and manipulates the moral judgment of LLMs via four adversarial strategies. It finds that both LLMs and guardrail models are highly vulnerable to morality attacks, and that larger models are paradoxically easier to compromise.
