Notion Says AI Chat Data Exposure Affected Fewer Than 1% of Workspaces

According to ChainCatcher, Notion said a data exposure involving AI chat records affected fewer than 1% of its workspaces and that it is notifying affected users. The company advised anyone who shared account details, passwords, or other credentials with its AI to treat them as compromised, check account login records, and change the credentials. The incident stemmed from a hack of service provider Fireworks. Notion used Fireworks AI to process data for Insights, a feature that helps workspace administrators understand team members’ AI usage, sending it stored AI conversations to generate analytics. Fireworks also provided inference services for some open-weight models in Notion products. The potentially exposed data mainly included users’ prompts and AI responses.
