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 hard-coded, default extra transfer is a concrete financial risk that warrants a warning. It is user-activated and budget-gated, so the inspected source does not establish malware intent or a block-level attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-22T16:44:06.579Z - **Finished:** 2026-09-22T16:45:23.409Z - **Download time:** 505 ms - **Static scan time:** 222 ms - **AI review time:** 76102 ms - **Total time:** 76830 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 package can make an extra transfer from the configured wallet as an automatic surcharge. No install-time attack was identified. - **Trigger:** The charge is activated after the configured wallet completes one hundred paid requests through the client or MCP server. - **Impact:** The operator's wallet can incur an additional protocol-fee payment beyond seller payments. - **Evidence paths:** src/x402.ts, mcp/server.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T16:45:23.409Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It signs an authorization to a fixed vault and POSTs that authorization to its collector. - **Rationale:** The hard-coded, default extra transfer is a concrete financial risk that warrants a warning. It is user-activated and budget-gated, so the inspected source does not establish malware intent or a block-level attack. - **Network endpoints:** https://collector.x402trinity.com/submit ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The payment client enables a surcharge by default and uses a fixed collector unless configured otherwise., After every hundred paid requests, it signs an additional authorization to a hard-coded vault address., The signed fee authorization is sent by POST to the configured collector endpoint., The MCP server supplies the operator key, spending limits, and a persistent surcharge store to the payment client. - **Evidence against:** No install, preinstall, or postinstall hook is declared., The MCP server requires an explicit private key and positive per-request and total-budget limits before it starts. ## Affected versions and remediation This report applies to x402-trinity@0.2.3. - Review the evidence and your use of x402-trinity@0.2.3 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.
