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): es6-promise is a well-known, benign Promise polyfill with no malicious history; not a meaningful attack vector for this package. ai
maintainer-change maintainer-added AI (maintainer-change): New maintainers dpup and medium are Dan Pupius and Medium org — directly tied to the package's own GitHub repo and author field. Legitimate organizational addition, not a suspicious takeover. ai
source-diff source-size-tripled AI (source-diff): 88x size increase is fully explained by bundling request and its transitive dependencies directly into the tarball. No obfuscation or malicious payload present. ai
source-diff large-new-source-files AI (source-diff): Size increase is due to vendored/bundled runtime dependencies (request and transitive deps), a known pattern for phantomjs-prebuilt. Not injected malicious code. ai
dependencies unvetted-dep:request AI (dependencies): request is a well-known HTTP client used to download prebuilt binaries; appropriate for this package's age and purpose. ai
install-scripts install-script:install AI (install-scripts): phantomjs-prebuilt's install script downloads prebuilt PhantomJS binaries; this is the package's documented and expected install flow. ai
provenance no-provenance AI (provenance): Legacy package predates Sigstore provenance; not a risk signal for established packages. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require loads platform-specific config by path in lib/util.js; standard pattern for this package. ai
semgrep semgrep:child-process-import AI (semgrep): child_process is used in install.js to verify the downloaded PhantomJS binary; standard for prebuilt binary packages. ai
