Data leaks from shared library list

My wife’s iPhone 16 Pro was just updated to iOS 27.01. She is getting data leaks to shared album randomly. It is people on her shared LIBRARY list (NOT shared album invitees). An iMessage she just received appeared in a shared album on another person’s iPhone on her shared library list and a spreadsheet stored on iCloud she accessed and printed. Has this happened to anybody else. I know of another person who has a shared library had two shared album leaked to somebody else who was not on the shared album invitees list nor the shared library though she had a shared library active.
