In Telerik JustDecompile versions prior to 2024 R1, a privilege elevation vulnerability has been identified in the applications installer component.  In an environment where an existing Telerik JustDecompile install is present, a lower privileged user has the ability to manipulate the installation package to elevate their privileges on the underlying operating system.

An issue found in Progress Telerik JustAssembly through 2018.1.323.2 and JustDecompile through 2018.2.605.0 makes it possible to execute code by decompiling a compiled .NET object (such as DLL or EXE) with an embedded resource file by clicking on the resource.
