Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): OpenZeppelin migrated to GitHub Actions CI publishing with SLSA provenance; this is a legitimate org-level change. ai
semgrep semgrep:api-obfuscation-reflect AI (semgrep): Reflect.get() used in a Proxy trap for method binding, not obfuscation; stable pattern in this codebase. ai
phantom-deps phantom-dep:undici AI (phantom-deps): undici is a declared runtime dependency in package.json; phantom-dep false positive. ai
dependencies unvetted-dep:@openzeppelin/defender-sdk-base-client AI (dependencies): First-party OpenZeppelin Defender SDK package; expected dependency for Defender integration features. ai
semgrep semgrep:dynamic-require AI (semgrep): The dynamic require is used in a tryRequire helper to probe for optional peer dependencies — a standard, benign plugin pattern with no arbitrary code execution risk. ai
dependencies unvetted-dep:@openzeppelin/defender-sdk-network-client AI (dependencies): First-party OpenZeppelin Defender SDK package; expected dependency for Defender network features. ai
dependencies unvetted-dep:@openzeppelin/defender-sdk-deploy-client AI (dependencies): First-party OpenZeppelin Defender SDK package; expected dependency for Defender deployment features. ai
dependencies unvetted-dep:ethereumjs-util AI (dependencies): ethereumjs-util is a well-known Ethereum ecosystem utility library; expected dependency for this plugin. ai
dependencies unvetted-dep:@openzeppelin/upgrades-core AI (dependencies): First-party OpenZeppelin package; core dependency of this official OpenZeppelin plugin. ai

v4.0.2

1 finding
INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v4.0.1

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v4.0.0

2 findings
HIGH Publisher changed: ericglau → GitHub Actions (on 2026-06-01) provenance

This version was published by a different npm account than previous versions on 2026-06-01. This could indicate a legitimate maintainer transition or an account compromise.

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v3.9.1

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
