Notepad++ is a free and open-source source code editor. An Unsafe Search Path vulnerability (CWE-426) exists in versions prior to 8.9.2 when launching Windows Explorer without an absolute executable path.

Under certain conditions, this could lead to arbitrary code execution in the context of the running application. Version 8.9.2 patches the issue.
