snyk@1.1307.1
snyk library and cli utility
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe installer is transparent and checksum-protected, with no observed self-dependency or broad project mutation. However, automatic delivery of an opaque executable at install time prevents a clean source-only verdict.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm installation triggers postinstall.
Impact
A remote executable is introduced during installation; opaque bundled artifacts also limit static assurance.
Mechanism
Remote binary download, local write, and executable permission change.
AI rationale
The installer is transparent and checksum-protected, with no observed self-dependency or broad project mutation. However, automatic delivery of an opaque executable at install time prevents a clean source-only verdict.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The postinstall hook runs a bootstrap path that downloads a platform executable.
- The wrapper fetches from Snyk download hosts, writes the response locally, and makes it executable.
- A SHA-256 comparison precedes the rename and permission change, but the downloaded executable remains outside this source review.
- The package includes a compressed NuGet archive and bundled zip-handling code, leaving opaque artifact behavior unresolved.
Evidence against
- No runtime dependency on this package name was found.
- The visible installer uses fixed Snyk hosts and a bundled expected checksum.
- No source evidence showed credential harvesting, broad project mutation, or AI-agent configuration writes.
