Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

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
publish-pattern new-deps-added AI (publish-pattern): nan is the standard Native Abstractions for Node.js library, expected for a node-gyp-based native addon like memcpy. Not a suspicious dependency addition. ai
install-scripts install-script:install AI (install-scripts): memcpy is a native C++ addon; node-gyp configure build is the standard and expected install script for compiling native bindings. ai
phantom-deps phantom-dep:nan AI (phantom-deps): nan is a native addon build dependency referenced in binding.gyp, not JS imports. This is standard for Node.js native addons. ai
phantom-deps phantom-dep:node-arraybuffer AI (phantom-deps): node-arraybuffer is used in native build configuration for this ArrayBuffer-focused package; phantom detection is a false positive for native addon deps. ai
