Shared Claude chats were reportedly showing up in search engines

Shared Claude conversations, plus some user-made documents and apps, were briefly indexed by search engines and surfaced in public search.

The sharing pages apparently lacked noindex protection, and some exposed content included crypto keys and legal prompts.

Anthropic appears to have fixed the issue quickly on Google, while Bing and Brave Search kept results visible longer.

The incident highlights a privacy failure in a widely used sharing feature that could expose sensitive user data.
