Notion disclosed that a security breach at its AI infrastructure provider, Fireworks AI, led to the exposure of AI chat transcripts from a small subset of Notion workspaces. The breach involved unauthorized access to Fireworks' development environment via a third-party cloud provider, compromising resource metadata, billing information, and datasets including Notion AI chat transcripts used in the Insights feature. Notion responded promptly by cutting off Fireworks' access, deleting data from vendor systems, and halting training runs. The exposed data was mostly unattributable, lacking user or workspace identifiers. Less than 1% of Notion users were impacted, and the Insights feature has been disabled. Users of affected workspaces are advised to review their data and rotate credentials if entered in chats.
