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 package provides authorization middleware and a client for Grant API checks. - **Trigger:** Application code calls an authorization method with a request. - **Impact:** The observed network activity supports the package's stated authorization purpose; no unrelated collection or automatic action was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T15:29:09.876Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client posts permission and context data to /api/auth/is-authorized at its configured apiUrl, using request-derived credentials when supplied. - **Rationale:** The entry points and client behavior match the package's stated server authorization purpose. No lifecycle hooks or unrelated credential collection were found in the inspected code. - **Network endpoints:** Configured apiUrl + /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 package identifies itself as a server SDK for Grant authorization middleware and guards., The main entry point exports GrantClient and error/token helpers from the client module., Authorization requests use the configured apiUrl and attach tokens or cookies from a caller-provided request. ## Affected versions and remediation This report applies to @grantjs/server@1.18.8. - Review the evidence and your use of @grantjs/server@1.18.8 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.
