Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 3.23.2 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The wallet-related scanner finding resolves to caller-triggered x402 payment behavior, with destination and amount taken from the payment challenge. The manifest has no install hook, and wallet migration is tied to explicit setup with adoption requiring an address. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-18T12:04:38.373Z - **Finished:** 2026-10-18T12:10:07.169Z - **Download time:** 506 ms - **Static scan time:** 2198 ms - **AI review time:** 326089 ms - **Total time:** 328796 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:** No attack was identified in the inspected source. The flagged wallet transfer is the SDK's per-call payment flow. - **Trigger:** A caller makes an API request and receives an HTTP 402 payment challenge. - **Impact:** The inspected path supports the package's payment function; it does not establish a publisher-directed wallet drain. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T12:10:07.169Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK signs a time-limited USDC authorization using the caller's configured wallet and the challenge's recipient and amount, then retries the request. - **Rationale:** The wallet-related scanner finding resolves to caller-triggered x402 payment behavior, with destination and amount taken from the payment challenge. The manifest has no install hook, and wallet migration is tied to explicit setup with adoption requiring an address. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json routes imports to the two inspected distribution entrypoints and lists build and development scripts, with no install lifecycle hook defined., The payment helper signs a time-limited USDC authorization from the caller's wallet to a recipient supplied to the helper; the ESM entrypoint checks the requested asset., In the CommonJS entrypoint, payment signing is reached after an HTTP 402 response. The recipient and amount come from the response's payment requirements., Wallet migration scanning is part of the explicit new agent wallet setup flow; migration lists discovered addresses, and adopting a wallet requires an address. ## Affected versions and remediation This report applies to @blockrun/llm@3.23.2. - Review the evidence and your use of @blockrun/llm@3.23.2 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.
