Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.12.0 - **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. The package reports resource and payment metadata to its service after successful payments, with capture enabled by default. The implementation provides an opt-out and says response bodies are not sent, but this runtime reporting is not disclosed in the user-facing quickstart, so warn for telemetry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-31T01:24:55.804Z - **Finished:** 2026-10-31T01:25:53.191Z - **Download time:** 777 ms - **Static scan time:** 788 ms - **AI review time:** 55819 ms - **Total time:** 57387 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:** Default runtime reporting sends payment and resource metadata to the package’s intel service; this warrants a warning as telemetry. - **Trigger:** A user runs twzrd-safe-fetch and its payment succeeds. - **Impact:** The service receives the resource URL and transaction metadata; response bodies are not included in the observation. - **Evidence paths:** dist/safe-fetch.js, dist/delivery-capture.js, dist/config.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T01:25:53.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The post-payment path sends a JSON delivery observation containing merchant and settlement identifiers, the resource URL, network, and delivery metadata to the configured intel endpoint. Capture is enabled unless explicitly disabled. - **Rationale:** The package reports resource and payment metadata to its service after successful payments, with capture enabled by default. The implementation provides an opt-out and says response bodies are not sent, but this runtime reporting is not disclosed in the user-facing quickstart, so warn for telemetry. - **Files touched:** dist/safe-fetch.js, dist/delivery-capture.js, dist/config.js - **Network endpoints:** https://intel.twzrd.xyz/v1/intel/delivery-observation ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After a successful safe-fetch payment, the code invokes delivery capture with the merchant wallet, resource URL, and network., The captured observation includes the merchant wallet, settlement transaction, resource URL, and delivery metadata., Capture POSTs the observation to the configured TWZRD intel service by default; an environment variable or option can disable it. - **Evidence against:** The capture is described as passive delivery evidence, and the implementation comments say response bodies are not shipped., The package provides an opt-out for delivery capture. ## Affected versions and remediation This report applies to twzrd-x402-gate@0.12.0. - Review the evidence and your use of twzrd-x402-gate@0.12.0 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.
