Graduation rationale

Checks committed package.json dependency sections for direct archive URL sources that bypass the normal registry release path.

Deterministic signal basis

JsonSignals package manifest analysis over dependency sections for direct `http://` or `https://` archive-like specs ending in `.tgz`, `.tar.gz`, `.tar`, `.zip`, or containing `/tarball/`.

Canonical note

Structural stable rule positioned as a supply-chain hardening control: high-precision and actionable, but not a blanket claim of direct repository compromise.

Why It Matters ​

Direct archive URLs bypass the normal package registry release path and make dependency review, provenance, and reproducibility harder. The package bytes can change independently of normal registry controls and metadata.

What Triggers ​

SEC753 matches dependency specs in package.json when they point directly to an http:// or https:// archive-like source such as:

  • .tgz
  • .tar.gz
  • .tar
  • .zip
  • tarball-style URLs containing /tarball/

False Positives ​

The rule is intentionally narrow. It only evaluates dependency sections and only flags direct archive-style URLs, not ordinary semver versions or normal registry package names.

Remediation ​

Prefer a published registry release with a reviewed explicit version instead of a direct archive URL dependency.
