Multiple Model Guardrail Jailbreak via Escalating Persona Tactic
A jailbreak vulnerability was discovered in multiple large language models from Alibaba and Anthropic that uses escalating role-play personas and obfuscated triggers to bypass safety guardrails and elicit prohibited content. The technique causes models to reclassify harmful requests as fictional or educational material.
What happened
