Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 9 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:** 1.23.1 - **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 inspected entry points and flagged Nest bundle implement a server authorization SDK: they extract request credentials and send permission checks to the configured Grant API. No install hooks, unrelated data collection, or concealed attack behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-11-01T20:27:41.058Z - **Finished:** 2026-11-01T20:28:19.898Z - **Download time:** 514 ms - **Static scan time:** 112 ms - **AI review time:** 38213 ms - **Total time:** 38840 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; the source fingerprint alert is not supported by the inspected behavior. - **Trigger:** Applications call the exported client or configure middleware and guards; authorization checks run when those integrations handle a request. - **Impact:** The inspected behavior supports the package's stated server authorization purpose; no unrelated data collection or account actions were found. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T20:28:19.898Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client sends a permission check and the request's Grant token to the caller-configured API URL. DEBUG\_GRANT only enables local debug logging. - **Rationale:** The inspected entry points and flagged Nest bundle implement a server authorization SDK: they extract request credentials and send permission checks to the configured Grant API. No install hooks, unrelated data collection, or concealed attack behavior was identified. - **Network endpoints:** Configured apiUrl (documentation examples use https://api.grant.com), path /api/auth/is-authorized ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The npm scripts are build, lint, type-check, and test commands; there are no lifecycle hooks., The Nest module creates its client only when the application calls forRoot(config)., The Nest guard checks the request token and configured permission before requesting authorization., The client posts the permission check to /api/auth/is-authorized and sends the request token to the configured apiUrl., The only environment variable read is DEBUG\_GRANT, which enables debug logging. ## Affected versions and remediation This report applies to @grantjs/server@1.23.1. - Review the evidence and your use of @grantjs/server@1.23.1 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.
