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.

SourceRuleReasonAccepted byWhen
typosquat typosquat.levenshtein:pg AI (typosquat): pbf is a well-established Mapbox Protocol Buffer library; the name similarity to 'pg' is coincidental and these serve entirely different purposes. ai
semgrep semgrep:new-function-constructor AI (semgrep): new Function() in compile.js is used to dynamically compile protobuf schemas — a standard, documented pattern for this type of code-generation library. ai

v5.1.0

2 findings
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

INFO Publisher changed: mbx-npm-08-production → mbx-npm-07-production (on 2026-05-29, known maintainer) provenance

This version was published by a different npm account (mbx-npm-07-production) than the most recent previously approved version (mbx-npm-08-production) on 2026-05-29, but mbx-npm-07-production is listed as a maintainer on prior approved versions (matched on name). This looks like a manual publish by a known maintainer rather than a publisher change. Recorded as INFO for audit trail.
