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
provenance publisher-changed AI (provenance): bcoe → oss-bot is a documented, legitimate transition for Ben Coe's packages to automated CI publishing. oss-bot has strong track record (368 approved). Stable for this package. ai
provenance missing-githead AI (provenance): Missing gitHead is consistent with the switch to automated oss-bot publishing environment. Not indicative of tampering for this package. ai
maintainer-change maintainer-added AI (maintainer-change): oss-bot added as maintainer is part of the legitimate bcoe → oss-bot automation transition. No compromise indicators. ai
publish-pattern new-deps-added AI (publish-pattern): @istanbuljs/schema is a legitimate Istanbul ecosystem package; adding it to a coverage tool is expected and benign. ai
phantom-deps phantom-dep:uuid AI (phantom-deps): uuid is properly declared in dependencies and used by c8; false positive for this package. ai
dependencies unvetted-dep:@c88/v8-coverage AI (dependencies): @c88 is Ben Coe's own npm scope (same author as c8); this is a first-party dependency, not a suspicious third-party package. ai
dependencies unvetted-dep:chrome-remote-interface AI (dependencies): chrome-remote-interface is the standard DevTools Protocol client; its use is expected and appropriate for a V8 coverage tool like c8. ai
dependencies unvetted-dep:spawn-wrap AI (dependencies): spawn-wrap is a well-known child process instrumentation utility; its use is expected for a coverage tool that wraps test runners. ai
typosquat typosquat.levenshtein:qs AI (typosquat): c8 is a well-known Node.js coverage tool, not a typosquat of qs. The name is intentional (C8/V8 coverage). ai
typosquat typosquat.levenshtein:pg AI (typosquat): c8 is a well-known Node.js coverage tool, not a typosquat of pg. The name is intentional (C8/V8 coverage). ai
semgrep semgrep:base64-decode AI (semgrep): Base64 decoding is used to parse base64-encoded source map data URIs, a standard and expected operation for a coverage/source-map tool. ai
