Discussing a potential bias in Llama2-Chat that can lead to content safety issues

[LLM-DRA]

We are raising a concern regarding the content safety of the model and seek the appropriate contact for reporting this issue. We have reviewed the use policy at https://ai.meta.com/llama/use-policy/, but the contact options listed there do not appear relevant to our concern.

We discovered that through specially crafted prompt, the model can output harmful instructions and them answer them, which voilates content safety. Moreover, we have implemented the code to automatically construct prompts given the harmful instruction and this method can compromise the safety fine-tuning of Llama2-chat and have it saying toxic content. We haven't released the code yet since we need to first disclose this issue with the model developers.
Specifically, if an attacker wants to manipulating Llama2-chat into cooperating with a certain harmful instruction, he or she can obfuscate the instruction and prompt the model to reconstruct the instruction and answer it. Here's an example:
