Local privilege escalation via code injection
Published Jul 14, 2026 · Updated Jul 14, 2026
Code injection in Microsoft .NET and .NET Framework allows local users to elevate privileges by inducing affected software to process crafted input. Microsoft has not disclosed the vulnerable component, input format, or operation that permits generated code to escape its intended restrictions. Exploitation requires user interaction and executes code with the privileges of the affected process, potentially granting elevated local access.
