Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff obfuscated-file:vendor/sinon/test/rhino/env.rhino.1.2.js AI (source-diff): This is the well-known Envjs browser environment library (MIT), vendored as a Sinon.js test dependency. Long lines are from minification, not obfuscation. Stable false positive for this package. ai
source-diff net-exec-file:vendor/sinon/test/rhino/env.rhino.1.2.js AI (source-diff): Envjs simulates browser networking and eval as its core purpose. Network+exec pattern is expected behavior for a browser environment emulator used in test infrastructure only. ai
source-diff large-new-source-files AI (source-diff): New files are vendored Sinon.js test suite files, a legitimate test dependency addition by a well-established publisher. ai
source-diff source-size-tripled AI (source-diff): Size increase is entirely attributable to vendoring the Sinon.js test suite including Envjs. No runtime payload concern. ai
semgrep semgrep:dynamic-require AI (semgrep): The dynamic require is a documented buster.js helper that only loads 'buster-*' sub-modules by design. It is not arbitrary module loading and poses no real risk. ai
bogus-package bogus-package AI (bogus-package): Package is ~14 years old and part of the legitimate buster.js testing framework. Sparse metadata is consistent with its age, not spam indicators. ai

v0.5.1

3 findings
HIGH New obfuscated file: vendor/sinon/test/rhino/env.rhino.1.2.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

HIGH New file with network + code execution: vendor/sinon/test/rhino/env.rhino.1.2.js source-diff

Newly added file contains both network calls and dynamic code execution. This is a hallmark of dropper/loader malware.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.3.0

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
