GHSA-r4pf-3v7r-hh55
electron-builder's NSIS installer - execute arbitrary code on the target machine (Windows only)
Quick fix
GHSA-r4pf-3v7r-hh55 — app-builder-lib: upgrade to the fixed version with the command below.
npm install app-builder-lib@24.13.2Details
### Impact Windows-Only: The NSIS installer makes a system call to open cmd.exe via NSExec in the `.nsh` installer script. NSExec by default searches the current directory of where the installer is located before searching `PATH`. This means that if an attacker can place a malicious executable file named cmd.exe in the same folder as the installer, the installer will run the malicious file.
### Patches Fixed in https://github.com/electron-userland/electron-builder/pull/8059
### Workarounds None, it executes at the installer-level before the app is present on the system, so there's no way to check if it exists in a current installer.
