Researchers demonstrate a critical vulnerability in diffusion-based language models where safety mechanisms can be bypassed by re-masking committed refusal tokens and injecting affirmative prefixes, achieving 76-82% attack success rates without gradient optimization. The findings reveal that dLLM safety relies on a fragile architectural assumption rather than robust adversarial defenses.

Researchers have developed a method to unlock prompt infilling capabilities in masked diffusion language models by extending full-sequence masking during supervised fine-tuning, rather than the conventional response-only masking.
