Authenticated privilege escalation via undisclosed authentication flaw
Published Jul 14, 2026 · Updated Jul 14, 2026
Improper authentication in Microsoft Azure Spring Apps before 7.3.0 allows remote authenticated users to elevate privileges over a network. Microsoft has not published the affected authentication component, rejected check, or request path that reaches the flaw. Low-privileged access and high-complexity conditions are required; exploitation crosses a security boundary, but the resulting role and permissions are undisclosed.
