CVE-2026-3224
Authentication bypass in the Microsoft Entra ID (Azure AD) authentication mode in Devolutions Server 2025.3.15.0 and earlier allows an unauthenticated user to authenticate as an arbitrary Entra ID user via a forged JSON Web Token (JWT).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
