Description: Users reported that publicly shared Claude Artifacts (apps, documents, spreadsheets, and other files) could be found through Google Search. Reportedly, indexed artifacts containing business plans, infrastructure diagrams, clinical-trial planning materials, and other potentially sensitive content were also located. Anthropic said links became searchable only after being posted somewhere crawlable.
Editor Notes: The incident ID date is 07/26/2026, when a Reddit user first publicly documented that shared Claude Artifacts could be located through Google Search (see https://www.reddit.com/r/ClaudeAI/comments/1v6yk7d/you_can_also_view_a_lot_of_shared_artifacts/). The artifacts may have been indexed earlier, but no exact initial-indexing date has yet been identified. The incident ID was created 08/06/2026.

Variants
A "variant" is an AI incident similar to a known case—it has the same causes, harms, and AI system. Instead of listing it separately, we group it under the first reported incident. Unlike other incidents, variants do not need to have been reported outside the AIID. Learn more from the research paper.
