Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via XAML parsing in Windows Presentation Foundation (WPF). An attacker can execute arbitrary code by supplying specially crafted XAML input that is processed by a vulnerable WPF application. Improper handling of XAML during parsing allows attacker-controlled content to trigger arbitrary code execution in the context of the current user.
