Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.9.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. No concrete malicious lifecycle, exfiltration routine, or stealth persistence was found. The explicit CLI nevertheless executes an unpinned third-party package with inherited environment, which warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-08T12:02:01.054Z - **Finished:** 2026-09-08T12:04:09.263Z - **Download time:** 505 ms - **Static scan time:** 469 ms - **AI review time:** 127233 ms - **Total time:** 128209 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The user-invoked safe-fetch command can download and execute agentcash@latest through npx. That external code receives the caller's inherited environment. - **Trigger:** Running twzrd-safe-fetch without providing a fixed agentcashPackage. - **Impact:** A compromised or changed agentcash release could execute with the invoking user's environment and permissions. - **Evidence paths:** dist/safe-fetch.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:04:09.263Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-triggered npx execution of an unpinned external package with inherited environment. - **Rationale:** No concrete malicious lifecycle, exfiltration routine, or stealth persistence was found. The explicit CLI nevertheless executes an unpinned third-party package with inherited environment, which warrants a warning. - **Files touched:** dist/safe-fetch.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The published command path can invoke a mutable external package through npx and passes the entire inherited environment to it., The package exposes this command as a bin executable, making the risky path directly user-invocable. - **Evidence against:** package.json has only a prepublishOnly hook, not an install-time lifecycle hook., The npx invocation is in an explicit safe-fetch CLI flow; no hidden import-time execution or foreign configuration mutation was found., The source labels the two-request payment path as advisory and exposes the challenge mismatch rather than concealing it. ## Affected versions and remediation This report applies to twzrd-x402-gate@0.9.3. - Review the evidence and your use of twzrd-x402-gate@0.9.3 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
