GoKawiilFireworks AI breach exposed Notion AI chat transcripts for some workspaces
Notion disclosed that a security breach at its AI infrastructure vendor Fireworks AI exposed Notion AI chat transcripts tied to its Insights feature in a small number of workspaces. Fireworks had suffered a prior October breach involving stolen API keys, then a second incident on October 23 where an attacker compromised metadata, billing details, model weights and datasets. Notion cut off Fireworks traffic and deleted vendor-held data by November 3, but Fireworks confirmed on November 8 that customer data, including Notion's, had actually been accessed.
