NPM's vulnerability profile centers on its package manager toolchain—the npm client, the tar extraction utility, the package dependency resolver (Arborist), and related Git integration libraries—which collectively form a critical node in the JavaScript supply chain. The recurring weakness classes cluster around file-system safety: path traversal, symlink-following, and improper pathname restrictions that arise when processing untrusted package archives and repository metadata, paired with information-disclosure flaws. A meaningful share of the vendor's disclosures reach serious severity, reflecting the consequences of archive-extraction and dependency-resolution flaws in build and deployment automation. Current exploitation activity and exposure counts are shown alongside this summary.
