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. 20 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 65.3.1 - **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected code shows Vercel-aligned authentication and CLI setup behavior, without evidence of an attack. The agent-configuration behavior and broader runtime paths remain unresolved, so a clean or warning verdict is not supported by this inspection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 52.0% - **Started:** 2026-10-26T17:23:58.127Z - **Finished:** 2026-10-26T17:32:51.876Z - **Download time:** 1028 ms - **Static scan time:** 10377 ms - **AI review time:** 522343 ms - **Total time:** 533749 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 concrete attack was established in the inspected excerpts, but this review did not resolve the package's broader runtime behavior. - **Trigger:** Unresolved; the reviewed excerpts do not establish an activating action for harmful behavior. - **Impact:** No confirmed attack impact was identified; broader behavior remains unresolved. - **Review source:** ai\_review - **Reviewed:** 2026-10-26T17:32:51.876Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The examined code shows CLI setup, Vercel authentication requests, and plugin-registry reading; it does not establish malicious effects. - **Rationale:** The inspected code shows Vercel-aligned authentication and CLI setup behavior, without evidence of an attack. The agent-configuration behavior and broader runtime paths remain unresolved, so a clean or warning verdict is not supported by this inspection. - **Files touched:** dist/chunks/chunk-PFPJLIFF.js, dist/commands-core.js - **Network endpoints:** https://api.vercel.com, Vercel SSO API endpoint ### Review decision - **Verdict:** Manual Review - **Confidence:** 52.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json identifies this as Vercel's JavaScript CLI package., The inspected plugin code reads Claude's installed-plugin registry; the excerpt does not establish what other setup code changes., The inspected core excerpt writes Vercel best-practices content to a target file, but does not establish how that target is selected or how the command is activated., The inspected AI setup path can recover a saved key, while the shown output path prints a newly created key only under specific conditions., The inspected OIDC refresh sends a bearer token to the Vercel API; the OpenAPI SSO request sends a Vercel token in a cookie to the SSO endpoint. - **Evidence against:** The reviewed excerpts do not establish credential transfer to an unrelated recipient or unconsented installation-time behavior. ## Affected versions and remediation This report applies to @vercel/cli-support@65.3.1. - Review the evidence and your use of @vercel/cli-support@65.3.1 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.
