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.

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff net-exec-file:jsdom/base.d.ts AI (source-diff): jsdom/base.d.ts is a TypeScript declaration file (.d.ts). References to network APIs and vm.Context are type signatures, not executable code. This is a stable false positive for DefinitelyTyped packages. ai
publish-pattern new-deps-added AI (publish-pattern): undici-types is the official TypeScript types for Node.js's undici HTTP client. Adding it is expected as jsdom adopted undici for fetch; legitimate dependency for this package. ai
phantom-deps phantom-dep:@types/node AI (phantom-deps): @types/node is used via triple-slash references in .d.ts files, standard DefinitelyTyped practice. Not a phantom dependency. ai
phantom-deps phantom-dep:@types/tough-cookie AI (phantom-deps): @types/tough-cookie is used via triple-slash references in .d.ts files, standard DefinitelyTyped practice. Not a phantom dependency. ai
