Claude Caught in Bizarre Loop, Allegedly Leaking Other Users' Chats
Notme_21 · reddit · 2026-07-30
A Reddit user reported alarming behavior from Claude when fed nonsensical prompts. Instead of failing gracefully, the model entered an endless generation loop, apologized, and accurately guessed the user's real name.
More concerningly, subsequent tests showed the model occasionally returning empty messages, while other times it leaked actual conversation fragments from different users. This cross-session data leakage has sparked significant privacy and security concerns within the community.
