Source: NotionAlso reported by SecurityWeek

Notion says its vendor Fireworks AI notified it of a security incident affecting fewer than 1% of Notion workspaces. As of November 3, Notion disconnected its systems from Fireworks, deleted the data held there and stopped sending it data and traffic. Notion found that data was retained from the Fireworks endpoints it used, although Fireworks had given a contractual commitment to zero data retention.

Why it matters

Affected workspace owners can review the exposed chat transcripts in a desktop browser, and Notion recommends rotating any credentials pasted into Notion AI during the period.
