Fireworks AI security breach impacts Notion and their customers

Fireworks AI, a vendor used by Notion for AI features, suffered a security breach that exposed unattributable chat transcripts from less than 1% of Notion workspaces. The exposed chats from Notion's AI Insights feature were not labeled with user or workspace information and contained no identifying data beyond the chat text itself. Notion has disabled the affected Insights feature and ceased using Fireworks for open-weight model serving, with affected workspace owners able to review the exposed data through their security settings.
