electron-builder's NSIS installer - execute arbitrary code on the target machine (Windows only)
### 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. ### References https://cwe.mitre.org/data/definitions/426.html https://cwe.mitre.org/data/definitions/427
