Notion AI chat transcripts exposed in Fireworks AI breach

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.
