twzrd-x402-gate@0.9.15

Security fixes: payment-verdict integrity issues fixed through 0.11.4 (see the 0.11.2, 0.11.3 and 0.11.4 changelogs). Upgrade to twzrd-x402-gate@0.11.4.

Released identity 0.9.15. Buyer-side x402 trust gate: free preflight before signing USDC to a merchant. On Solana mainnet and Base mainnet (eip155:8453), a missing payTo is not approved, a buyer preflight outage does not sign unless TWZRD_FAIL_OPEN=true,

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The package’s import entry point re-exports library modules, while the flagged process execution and diagnostic behavior are tied to explicit CLI use. Its only lifecycle script is prepublishOnly, which is not an install hook.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user runs a package CLI or calls its library functions.

Impact

No malicious behavior was identified. The safe-fetch preflight is documented as advisory and does not guarantee the later payment matches the checked request.

Mechanism

The safe-fetch CLI probes a user-provided URL and may invoke AgentCash; the doctor reads the operator’s manifest and performs a local refusal proof by default.

AI rationale

Network endpoints1

intel.twzrd.xyz

Decision evidence

public snapshot

AI called this Clean at 93.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest exposes the library entry point and CLI binaries; its only lifecycle script is prepublishOnly.
The safe-fetch module describes its payment check as an advisory preflight and documents the mismatch risk between the checked request and the later payment request.
safe-fetch runs its CLI main function only when executed directly.
The doctor says its refusal proof uses no network by default; its binary calls that function only when the doctor CLI is run.

Evidence against

Running safe-fetch can invoke npx to run AgentCash with the caller’s request, headers, and environment.
The doctor reads the operator’s package.json when explicitly run.
