i had the exact same behavior back in 2023, it seemed like clearly leakage of user conversations - but it was just a bug with api calls in the software i was using.
It was the classic "oh no we did caching wrong" bug that many startups bump into. It didn't expose actual conversations though, only their titles: https://openai.com/index/march-20-chatgpt-outage/

I felt like it was a huge deal at the time but it’s surprisingly hard to quickly google it.
