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 flagged Nest bundle contains ordinary framework integration code, and the client sends request credentials only with authorization requests to the configured Grant API URL. The manifest declares no install hook or import-time collector. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-11-04T10:42:21.115Z - **Finished:** 2026-11-04T10:43:11.893Z - **Download time:** 512 ms - **Static scan time:** 107 ms - **AI review time:** 50158 ms - **Total time:** 50778 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 identified; the package provides server-side authorization checks for web frameworks. - **Trigger:** Application code imports an integration and invokes its middleware, guard, or GrantClient authorization method. - **Impact:** The service receives the authentication and authorization data needed to evaluate the requested permission; no unrelated collection or attack behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T10:43:11.893Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client sends permission details and, when provided, the incoming request's token or cookie to the configured Grant API URL. - **Rationale:** The flagged Nest bundle contains ordinary framework integration code, and the client sends request credentials only with authorization requests to the configured Grant API URL. The manifest declares no install hook or import-time collector. - **Network endpoints:** User-configured apiUrl; api.grant.com appears as a documented example ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes a server authorization SDK and exports framework integrations; it declares no install lifecycle hooks., The package scripts are build, type-check, lint, and test commands., Authorization calls POST permission and resource context to the configured Grant API endpoint., The client forwards a request token and cookie as authorization inputs for that API call., The flagged Nest bundle contains framework decorators and imports the Grant client and debug helper. ## Affected versions and remediation This report applies to @grantjs/server@1.25.0. - Review the evidence and your use of @grantjs/server@1.25.0 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.
