Vulnerability Type: Unpinned third-party dependency
Risk Level: MediumVulnerable Code Snippet:
text Use Viem library to interact with ERC-8004 smart contracts. Install viem package first.Technical Analysis
The Skill instructs the user or agent to install Viem without specifying an exact version, lockfile, integrity hash, package source, or reproducible installation procedure. This leaves dependency resolution dependent on package-registry state at installation time.
Viem is security-critical in this workflow because it creates the local wallet account from
PRIVATE_KEY, signs blockchain transactions, and submits calls to the ERC-8004 registry. Although no malicious package is embedded in the audited project, an unconstrained installation can resolve to an unexpectedly changed or compromised dependency version.Attack Path
- An attacker compromises the package, a transitive dependency, or the dependency distribution channel.
- The user or agent follows the instruction to install Viem without an exact version or trusted lockfile.
- The package manager resolves and executes the affected package version during installation or runtime.
- The dependency runs in the Node.js process used for wallet and transaction operations.
- Malicious code accesses signing material available to that process, modifies transaction parameters, or initiates unauthorized network activity.
This path requires compromise or manipulation of the external dependency supply chain; the audited file does not itself contain a malicious payload.
Impact Assessment
A compromised dependency could obtain the privileges of the Node.js process. In the intended workflow, this may include access to the dedicated wallet's
PRIVATE_KEY, its available ETH, ownership-management capabilities for ERC-8004 NFTs, the Pinata JWT if exposed to the same process, and accessi ...[truncated 264 chars]- Remediation

Remediation Suggestions
- Pin Viem to a reviewed exact version rather than requesting an unspecified release.
- Include a committed package manifest and lockfile containing package integrity metadata.
- Require deterministic installation with
npm cior an equivalent frozen-lockfile mechanism. - Document the expected package registry and reject alternate or untrusted package sources.
- Run dependency vulnerability and provenance checks before installation and periodically review updates.
- Upgrade only through an explicit review process that checks release changes and regenerated lockfile entries.
- Keep the signing process isolated and expose only the minimum required environment variables.
- Continue requiring a dedicated wallet with minimal funds and a narrowly scoped Pinata credential to limit the consequences of dependency compromise.
