Multi-agent framework jailbreaks LLMs via moral foundations theory
Start here
A study released on arXiv on October 14, 2026, proposes a multi-agent framework based on Moral Foundations Theory (MFT): agents first determine which moral foundation a harmful request violates, then identify a foundation that could make the same request seem justified and rewrite the prompt accordingly, and also reinforce it with generated precedents of similar moral reframing, thereby bypassing model safety guardrails. Testing five open-source and closed-source models on harmful prompts from three well-known jailbreak datasets, the results show that models are highly sensitive to moralization, with a high jailbreak success rate on a single attempt, which further increases after repeated attempts. The analysis also finds that the moral foundations violated in safety benchmarks are unevenly distributed.

The researchers propose a multi-agent framework based on Moral Foundations Theory (MFT) that rewrites initially rejected harmful requests into morally justified versions to bypass model safety guardrails. The framework has agents first determine which moral foundation the request violates, then identify a foundation that could make the same request seem justified, and rewrite the prompt accordingly, reinforced with generated precedents of similar moral reframing. Testing five open-source and closed-source models on harmful prompts from three well-known jailbreak datasets, the results show that models are highly sensitive to moralization, with high jailbreak success rates on single attempts that increase further with repeated attempts. The analysis also finds that the distribution of moral foundations violated by safety benchmarks is imbalanced, concentrated on foundations for which models already exhibit preferences.
