Why flagged

The PKGBUILD installs Node.js packages via yarn during prepare(), including an undeclared external package 'semver' added with 'yarn add -D', which poses a supply-chain risk if the registry is compromised.

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:149 yarn add -D semver
Medium AI review llm_review

An AI model (qwen/qwen3-235b-a22b-2507) reviewed this and agrees it is MEDIUM (confidence 85%): The PKGBUILD installs Node.js packages via yarn during prepare(), including an undeclared external package 'semver' added with 'yarn add -D', which poses a supply-chain risk if the registry is compromised.

  • PKGBUILD:98 npm install -g "@yarnpkg/cli-dist@${_yarnver}" --prefix "${_yarnhome}" --registry "${npm_config_registry}"
