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:** 0.1.2 - **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 source matches the package’s stated Next.js policy-integration purpose and contains no install hook or unrelated data collection. Its optional counters are documented, send only when a Posterna site key is configured, and can be disabled. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-29T16:41:58.258Z - **Finished:** 2026-10-29T16:42:50.629Z - **Download time:** 513 ms - **Static scan time:** 62 ms - **AI review time:** 51796 ms - **Total time:** 52371 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 package applies request policy and offers documented, site-key-gated counters. - **Trigger:** Policy loading occurs when the adapter is created; counters record requests during adapter use and transmit only when a site key is configured. - **Impact:** Applies the configured policy and, when enabled by a site key, shares aggregated request metrics with Posterna. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T16:42:50.629Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Reads the configured policy file. Counters aggregate verdict and policy buckets and send them to the Posterna service; they can be disabled with counters: false. - **Rationale:** The source matches the package’s stated Next.js policy-integration purpose and contains no install hook or unrelated data collection. Its optional counters are documented, send only when a Posterna site key is configured, and can be disabled. - **Files touched:** agents.yaml (read by default; configurable via policyPath or POSTERNA\_POLICY) - **Network endpoints:** https://posterna.com/v1/ingest ### 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 Next.js policy integration and declares no lifecycle scripts; its scripts are build and typecheck., At runtime, the adapter reads the configured policy file, defaulting to agents.yaml, to create the policy engine., The adapter sets up counters by default but supports disabling them with counters: false., The dependency documents that counters aggregate request buckets and send them to the Posterna cloud only when POSTERNA\_SITE\_KEY is configured; without a key, nothing is sent., The counter payload is POSTed to the configured base URL’s ingest path with the site key as a bearer token. ## Affected versions and remediation This report applies to @posterna/next@0.1.2. - Review the evidence and your use of @posterna/next@0.1.2 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 3. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 4. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 5. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 97.0% - **Path:** package.json - **Public source:** [View source]() The manifest describes a Next.js policy integration and declares no lifecycle scripts; its scripts are build and typecheck. Public source snippet (untrusted): ```json "name": "@posterna/next", "version": "0.1.2", "description": "Next.js integration for Posterna: verify AI agents and crawlers and apply policy.", "keywords": [ "ai-agen ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 97.0% - **Path:** dist/index.js - **Public source:** [View source]() At runtime, the adapter reads the configured policy file, defaulting to agents.yaml, to create the policy engine. Public source snippet (untrusted): ```javascript const read = readPolicyFile(options.policyPath ?? env.POSTERNA_POLICY, warn); policyLoad = read.problem ? { source: "fallback", problem: read.problem } : { source: "file", problem: nul ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 97.0% - **Path:** dist/index.js - **Public source:** [View source]() The adapter sets up counters by default but supports disabling them with counters: false. Public source snippet (untrusted): ```javascript , env }); } let counters = null; if (options.counters !== false) { try { counters = createCounters({ siteKey: options.siteKey, baseUrl: options.baseUrl, env, onError: warn, ...options.counters ?? {}, sdk: { name: "@posterna/next", versi ``` ### 8. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 97.0% - **Path:** .lpm-dependency-evidence-49bbf947-9502-45e1-9536-d8dad1cb0f9f/0/npm-linux/README.md - **Public source:** [View source]() The dependency documents that counters aggregate request buckets and send them to the Posterna cloud only when POSTERNA\_SITE\_KEY is configured; without a key, nothing is sent. Public source snippet (untrusted): ```markdown ## Counters `createCounters({ sdk, source: engine })` aggregates requests by hour, verdict, reason code, operator, agent, purpose, path group, action and enforced. With a site key (`POSTERNA_SITE_KEY`) it sends them to the Posterna cloud every 60 seconds and on exit, and applies the cloud's monitor override to the engine. Without one it sends nothing. Recording never blocks or slows a request, and no address, URL or header value is ever kept or sent. The adapters set this up for you. Signature ``` ### 9.
