Provenance
Supply chain provenance
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.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| dependencies | unvetted-dep:react-is-18 | AI (dependencies): npm alias for canonical react-is@^18.3.1; legitimate multi-React-version support pattern. | ai | |
| dependencies | unvetted-dep:react-is-19 | AI (dependencies): npm alias for canonical react-is@^19.2.5; legitimate multi-React-version support pattern. | ai | |
| source-diff | net-exec-file:build-es5/index.js | AI (source-diff): build-es5/index.js is the documented browser entry point — a UMD bundle with core-js polyfills. The 'network+exec' pattern is the standard global-detection idiom (Function('return this')()) in polyfill code, not malware. | ai | |
| provenance | missing-githead | AI (provenance): pretty-format is a long-established Jest package; missing gitHead reflects a publish environment change, not a security concern. Stable false positive for this package. | ai | |
| phantom-deps | phantom-dep:@jest/types | AI (phantom-deps): Framework-scoped Jest package loaded by convention; phantom status is expected and benign. | ai | |
| source-diff | source-size-tripled | AI (source-diff): Legitimate growth from v22 to v24; consistent with feature additions and build artifacts. | ai | |
| dependencies | unvetted-dep:@jest/types | AI (dependencies): @jest/types is a core Jest package; unvetted status is expected for internal monorepo dependencies. | ai | |
| source-diff | large-new-source-files | AI (source-diff): Expected growth for a two-version bump with feature additions; no evidence of injected code. | ai | |
| maintainer-change | maintainer-takeover | AI (maintainer-change): The maintainer transition reflects the well-documented handoff of the Jest project to the Facebook/Meta team. The new maintainers (simenb, aaronabramov, fb, etc.) are the official Jest maintainers at Facebook. This is not a hijack. | ai | |
| provenance | no-provenance | AI (provenance): Provenance absence is expected for packages predating Sigstore adoption; not a security risk. | ai | |
| provenance | publisher-changed | AI (provenance): Publisher change reflects documented Jest maintainer transition in 2020; stable for this package. | ai | |
| maintainer-change | maintainer-added | AI (maintainer-change): Maintainer additions are part of documented Jest project transition; stable for this package. | ai | |
| maintainer-change | maintainer-removed | AI (maintainer-change): Maintainer removal is part of documented Jest project transition; stable for this package. | ai | |
| publish-pattern | new-deps-added | AI (publish-pattern): New dependencies are all established packages appropriate for a formatting utility. | ai | |
| semgrep | semgrep:new-function-constructor | AI (semgrep): new Function() is in a performance test with explicit eslint-disable; legitimate test case, not code execution risk. | ai | |
| dependencies | unvetted-dep:@jest/schemas | AI (dependencies): @jest/schemas is a first-party Jest monorepo package versioned in lockstep with pretty-format; not a suspicious third-party dependency. | ai |
