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. 10 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:** 1.25.30 - **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 reviewed code matches the package’s stated purpose: it instruments a Vite-served app and forwards browser events to a local LensMCP bridge. Replay uses that same host and port, with an option to disable it; no unrelated external endpoint or harmful behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-29T06:46:39.340Z - **Finished:** 2026-10-29T06:49:54.304Z - **Download time:** 513 ms - **Static scan time:** 57 ms - **AI review time:** 194392 ms - **Total time:** 194964 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 inspected runtime behavior supports the package’s Vite browser-event bridge and session replay features. - **Trigger:** Vite dev-server startup injects the browser client; replay runs when enabled by the plugin’s replay setting. - **Impact:** No external data exfiltration or unrelated harmful action was identified in the inspected paths. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T06:49:54.304Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The browser client connects to the plugin’s token-protected local bridge and sends event data there. Replay uploads use the bridge host and port. - **Rationale:** The reviewed code matches the package’s stated purpose: it instruments a Vite-served app and forwards browser events to a local LensMCP bridge. Replay uses that same host and port, with an option to disable it; no unrelated external endpoint or harmful behavior was identified. - **Network endpoints:** ws://127.0.0.1:\ (default host; configurable via wsHost), http://127.0.0.1:\ (replay endpoint; default host configurable via wsHost) ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package describes itself as a LensMCP Vite plugin providing a browser event bridge and identifies its repository as the LensMCP project., When Vite configures the dev server, the plugin creates a bridge with a random token; the bridge checks allowed origins and validates the token on connections., The replay client is configured to send to an HTTP endpoint built from the bridge host and port, and its uploader uses POST requests. The default host is local, and the host is configurable., Replay can be disabled with LENSMCP\_REPLAY=0/off/false or with the plugin option. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.30. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.30 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.
