Security Incidents:

  • No major breaches of Notion infrastructure identified. In 2025, security researchers disclosed prompt injection risks in Notion AI agents that could enable data exfiltration via crafted workspace content (CVE-2024-23745 also affected Notion Web Clipper 1.0.3). These are configuration and feature-level risks, not infrastructure compromises.
