   Notion said a Fireworks AI incident affected under 1% of Notion workspaces, with the impacted dataset including Notion AI chat transcripts used for the Insights feature that were largely unattributable to users or workspaces. Notion disconnected from Fireworks on 3 November, deleted its data there, disabled Insights, and stopped serving open-weight models through Fireworks; it contacted affected customers on 9 November. Affected customers can retrieve the data in their workspace and are advised to treat it as exposed and rotate any sensitive information, passwords or API keys pasted into Notion AI during the incident timeframe.

   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.
