Microsoft Copilot Studio: Enforce safe sharing by detecting credential oversharing

🚨 The Signal: Copilot Studio now detects and prevents sharing of agents and flows that use unsafe maker credentials. This reduces identity leakage and privilege escalation risks by enforcing safe-sharing policies at publish and share time.

The Impact

Copilot Studio makers and administrators are affected, reducing the risk of identity leakage and privilege escalation.

  • Makers: May be blocked from sharing agents/flows with unsafe credentials.
  • Administrators: Gain new controls to enforce secure sharing policies.
  • Security Teams: Reduced risk of credential oversharing and privilege escalation.
  • Organisations: Improved security posture against identity leakage.

The Action

  1. Review Copilot Studio Data Loss Prevention (DLP) policies for connectors and environments.
  2. Educate makers on secure identity practices for Copilot Studio connections.
  3. Monitor Copilot Studio audit logs for sharing policy enforcement events.
  4. Assess existing Copilot Studio agents/flows for reliance on maker credentials.
