Security Vulnerability: Can see other peoples' cloud documents

I'm not sure exactly what caused this, but I was recently able to see other people's documents in my recently modified tab in photoshop. I previously had a creative cloud subscription on a personal account, but I recently migrated to using a school account since they provide a student license. When I opened the photoshop app after migrating, all of the suggestions that pointed to locally saved files were still there. However, the files that were marked as "CLOUD DOCUMENT" were replaced by random files that I had never seen before. I opened one of them up, and it seemed that they were most likely other people's files. After closing they were removed from my suggestions list, but it is probably possible to save these files locally to my computer. This seems like a huge security issue and I hope it's reported to the revelant personnel. Not sure if I can fully reproduce the bug as it most likely originated from changing accounts. I have attached a screenshot showing the unknown file listed under recent. (The top listing was created after opening the file on my computer.)
