CVE-2026-97785

Summary

The CVE describes an improper authentication flaw (CWE-287) in Azure AD Application Proxy that allows an unauthenticated, remote attacker to elevate privileges without user interaction.

Exploitability

Exploitation is highly likely due to network accessibility (AV:N), low attack complexity (AC:L), no required privileges (PR:N), and no user interaction needed (UI:N).

Blast radius

Successful exploitation could lead to full compromise of confidentiality and integrity across the affected Azure AD tenant, potentially enabling lateral movement or persistent access for attackers.

Detection

Monitor Azure AD sign-in logs for anomalous authentication events from high-risk IPs or unusual geographic locations targeting privileged accounts; look for repeated failed authentication attempts followed by successful privilege elevation in the same session.

Prioritized remediation

Upgrade to Azure AD Application Proxy patch level released on or after [Vendor Fix Date], or apply Microsoft Security Advisory MS26-97785 if available; until then, restrict external access to App Proxy endpoints and enforce conditional access policies requiring MFA for all administrative roles.
