Risky Entra apps can lose access tokens within minutes
Reviewed by Helen Jones
Microsoft updated guidance for Continuous Access Evaluation (CAE) on service-principal access tokens. For supported workload identities that request the cp1 client capability, high-risk, disabled, or deleted service principals can have Microsoft Graph access invalidated within minutes instead of waiting for a normal 60–90 minute token expiry. The feature has scope and licensing limits: it targets supported single-tenant applications and Microsoft Graph, and a high-risk block needs Conditional Access for workload identities.
A compromised application identity can hold powerful Microsoft Graph permissions while its access token remains valid. An incident response plan that only changes a secret or waits for token expiry leaves a window in which automated access can continue. CAE gives SharePoint and Teams administrators a faster containment path, but it is not a universal switch. The application must request CAE-capable tokens, and the policy, licence, supported resource, and response runbook all need to line up before an incident.
Analysis
Pick one non-production, single-tenant app that calls Microsoft Graph. Check its Entra service-principal sign-in logs for the CAE field, then have the identity and security owners validate the disable-and-recover runbook before relying on it in an incident.
