CVE-2026-114162

Summary

A privilege escalation flaw in Microsoft Graph due to incorrect authorization (CWE-863) allows an authenticated attacker with high privileges to gain elevated access over the network. This enables unauthorized actions beyond the attacker's assigned permissions.

Exploitability

Exploitation requires a pre-existing high-privilege account and network access; no public exploit exists, suggesting moderate technical skill is required.

Blast radius

Successful exploitation could lead to full compromise of tenant data, unauthorized administrative actions, and lateral movement across Microsoft 365 services.

Detection

Monitor Azure AD audit logs for anomalous privilege elevation events (e.g., 'Add member to role' or 'Update directory role') performed by users without expected administrative permissions; correlate with Microsoft Graph API telemetry showing unexpected scope expansion in token requests.

Prioritized remediation

Apply the Microsoft security update released for CVE-2026-114162; as no fixed version is specified in the description, immediately enforce least-privilege access controls and review all high-privilege user assignments per Microsoft’s authorization guidance.
