Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The default replay behavior creates a meaningful privacy risk because it records unmasked inputs, including passwords. The bridge defaults to loopback and the source does not establish unrelated external exfiltration, so this warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-25T19:18:50.274Z - **Finished:** 2026-10-25T19:21:00.685Z - **Download time:** 778 ms - **Static scan time:** 53 ms - **AI review time:** 129579 ms - **Total time:** 130411 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:** The Vite plugin enables session replay by default in development and records page activity with inputs, including password fields, unmasked. Replay data is sent to the plugin's local bridge; the inspected source does not establish an external recipient. - **Trigger:** A project runs Vite serve with the plugin enabled and no replay opt-out configured. - **Impact:** Sensitive text entered into the observed page may be sent to the local collector without a separate replay opt-in. - **Evidence paths:** lib/plugin.js, lib/replay-setting.js, .lpm-dependency-evidence-6842f6c2-ab98-4541-8202-0268e402dbc7/1/npm-linux/replay-source.js - **Review source:** ai\_review - **Reviewed:** 2026-10-25T19:21:00.685Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin injects a browser recorder; its defaults leave inputs unmasked and it posts replay chunks to the bridge host and port. - **Rationale:** The default replay behavior creates a meaningful privacy risk because it records unmasked inputs, including passwords. The bridge defaults to loopback and the source does not establish unrelated external exfiltration, so this warrants a warning rather than a publish block. - **Network endpoints:** http://127.0.0.1:\/replay (default host), http://\:\/replay ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The plugin is enabled by default for Vite serve and defaults its bridge host to 127.0.0.1; it starts that bridge and injects the client., Replay is enabled when no disabling environment setting or capture-file value is present, and the plugin injects the replay module when replay is enabled., The recorder defaults to leaving inputs unmasked and explicitly disables password masking; it captures page events for replay., Replay chunks are posted to an endpoint derived from the plugin host and port. This can expose sensitive page input to the local collector., The publish-event mapper filters sources through a predicate, sanitizes titles and messages, and redacts raw network URLs in the returned event record. - **Evidence against:** The replay destination uses the plugin's configured host and port, which default to 127.0.0.1; the inspected source does not establish transfer to an unrelated external service. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.26. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.26 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.
