Tell HN: Notion AI chat sessions have been exposed via Fireworks AI hack

A Notion email to affected customers says a security incident at vendor Fireworks AI may have exposed data, and that Notion shut down all connections to Fireworks' systems as a precaution. On November 6 Fireworks notified Notion that malicious actors may have accessed potential customer data, and on November 8 confirmed a new dataset that included unattributable Notion AI chat transcripts used for the Insights feature, without labels identifying the author or workspace and without tool call results. Notion says the Insights feature has been disabled during the investigation and that it no longer serves open-weight models through Fireworks.
