MEDIUM

Why flagged The PKGBUILD pulls electron and electron-packager from npm at build time (npm install electron electron-packager) without pinning versions or providing checksums. These are large, complex packages (electron especially bundles a full Chromium build) fetched from the npm registry at whatever version npm resolves to. The resulting Electron binary is then executed via npx electron-packager to produce the final packaged application. While npm/electron are well-known packages and this is a common Electron app packaging pattern, the lack of any version pinning or integrity verification means a compromised or malicious version of either package could execute arbitrary code during the build. This is a genuine supply-chain concern: undeclared external binary dependencies fetched and executed without checksums. The source repo itself is a personal GitHub project (not an official vendor), and the sha256sums is SKIP. This is a real medium-severity supply-chain risk, not a false positive.

Triggered rules

MEDIUM npm/yarn/pnpm install of an undeclared external package npm_install_external

Runs `npm/yarn/pnpm install <package>` for a package not in source=(), pulling unpinned, unreviewed code at build time. Severity downgraded: the package declares/looks like a Node.js consumer, where build-time installs are expected.

PKGBUILD:26 npm install electron electron-packager

MEDIUM npx/bunx/deno executes a remote package remote_code_tool

`npx`/`bunx`/`pnpm dlx`/`deno run <url>` downloads AND runs a remote package at build time — the moral equivalent of piping a download into a shell. Severity downgraded: Node.js consumer context.

PKGBUILD:27 npx electron-packager . --overwrite --platform=linux --output=release-build --prune=true
