This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Notepad++ is a free and open-source source code editor. From 8.9.4 until 8.9.6, Notepad++ contains a local privilege escalation vulnerability in the installer. During installation, the installer invokes powershell.exe without using an absolute path after setting the working directory to the installation contextMenu directory. If an attacker can pre-place a malicious powershell.exe in a user-writable custom installation directory, and a privileged user later runs the installer and selects that directory, the attacker-controlled executable is launched with the elevated privileges of the installer. This vulnerability is fixed in 8.9.6.
Remediation
Check the references section for vendor advisories and patches from notepad-plus-plus. Update notepad\+\+ to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
