EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 97% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Notepad++ is a free and open-source source code editor. Prior to 8.9.7, the Notepad++ Windows 11 x64 and ARM64 installer passes the attacker-influenced installation directory $INSTDIR from PowerEditor/installer/nppSetup.nsi into a PowerShell -Command string used by RegisterMSIX to invoke Add-AppxPackage, allowing PowerShell subexpression syntax such as $() in the installation path to execute commands in the installer's security context when the context menu component is selected. This issue is fixed in version 8.9.7.
