@adulau Of course not. The responsible thing, which Google notably didn't do, would be to say "there's a way to extract PII and verbatim data from LLMs, including ChatGPT" back in August.

  Extracting Training Data from ChatGPT
  I’m wondering if OpenAI requested a CVE for the disclosure of this vulnerability.

    Scalable Extraction of Training Data from (Production) Language Models
    
    This paper studies extractable memorization: training data that an adversary can efficiently extract by querying a machine learning model without prior knowledge of the training dataset. We show an adversary can extract gigabytes of training data from open-source language models like Pythia or GPT-Neo, semi-open models like LLaMA or Falcon, and closed models like ChatGPT. Existing techniques from the literature suffice to attack unaligned models; in order to attack the aligned ChatGPT, we develop a new divergence attack that causes the model to diverge from its chatbot-style generations and emit training data at a rate 150x higher than when behaving properly. Our methods show practical attacks can recover far more data than previously thought, and reveal that current alignment techniques do not eliminate memorization.
