Highest confirmed finding severity

High

2 confirmed security findings require attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives caused by Markdown code fences and escrow identifiers. The skill genuinely handles wallet private keys and directs irreversible on-chain transactions without confirmation safeguards. It should protect secrets and require explicit approval before each transaction.

Capability review items (1)
High
SKILL.md:90
Generic API/secret keys
- Private key set via `nla wallet:set`, `--private-key` flag, or `PRIVATE_KEY` env var
The skill recommends using a PRIVATE_KEY environment variable. A wallet private key is highly sensitive and the guidance does not address secure handling.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (2)

RISK-001 High
SKILL.md:90
Crypto seed/private key mention
- Private key set via `nla wallet:set`, `--private-key` flag, or `PRIVATE_KEY` env var
The skill instructs users to provide a wallet private key through an environment variable or CLI flag. This can expose credentials through logs, shell history, or agent context.
RISK-002 High
SKILL.md:39-55SKILL.md:67-77
Irreversible On-Chain Actions Lack Confirmation
The workflow directs submission, bonding, and token collection without requiring explicit user confirmation immediately before transactions. These actions can spend gas, create permanent on-chain records, and transfer tokens.
The documented commands submit a bonded fulfillment and transfer escrowed tokens, yet no confirmation checkpoint appears before either external action.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    High
    Private-key handling guidance permits insecure disclosure paths.
    Never request or display private keys. Prefer an external wallet signer, and warn that CLI flags and environment variables can leak through history, logs, and process inspection.
  2. FIX-002
    High
    On-chain fulfillment and collection can execute without an explicit approval checkpoint.
    Show the escrow UID, chain, oracle, wallet address, token amount, gas impact, and permanent-data warning, then require explicit confirmation immediately before each transaction.
