koffi — Greenflagged

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.

Source	Rule	Reason	Accepted by	When
install-scripts	install-script:install	AI (install-scripts): Install script invokes cnoke.js with --prebuild flag to select prebuilt native binaries. Standard pattern for native addon packages; stable across all koffi versions.	ai	2026/04/27
npm-metadata	bundled-binaries	AI (npm-metadata): Koffi ships prebuilt .node binaries for 18 platform/arch combinations as its documented distribution model. These are the legitimate FFI native addon artifacts.	ai	2026/04/27
semgrep	semgrep:eval-usage	AI (semgrep): eval('require')(filename) is a standard bundler-bypass pattern used to dynamically load platform-specific .node binaries at runtime. Not an arbitrary code execution risk in this context.	ai	2026/04/27
semgrep	semgrep:child-process-import	AI (semgrep): child_process is used in the cnoke build tool (builder.js) to invoke CMake/compiler toolchains. Expected and necessary for a native addon build system.	ai	2026/04/27
