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 browser capture and replay delivery to a configurable LensMCP bridge, with replay requests omitting credentials. However, the selected @lensmcp/core dependency source was unavailable, preventing assessment of the imported redaction helper; manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-22T16:04:07.750Z - **Finished:** 2026-10-22T16:04:51.890Z - **Download time:** 1274 ms - **Static scan time:** 170 ms - **AI review time:** 42695 ms - **Total time:** 44140 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 in the inspected runtime. Review remains unresolved because the source for a selected dependency used during replay sanitization was unavailable. - **Trigger:** Importing and using the replay functionality invokes the dependency's URL redaction helper. - **Impact:** The dependency's behavior could not be assessed, so a clean verdict cannot be established from this snapshot. - **Evidence paths:** package.json, lib/replay/anchors.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T16:04:51.890Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package imports redactUrl from @lensmcp/core/redact, but that dependency source was not present for inspection. - **Rationale:** The inspected code shows browser capture and replay delivery to a configurable LensMCP bridge, with replay requests omitting credentials. However, the selected @lensmcp/core dependency source was unavailable, preventing assessment of the imported redaction helper; manual review is warranted. ### Review decision - **Verdict:** Manual Review - **Confidence:** 79.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package depends on @lensmcp/core@1.25.22, whose source could not be inspected in this snapshot., The runtime imports redactUrl from that dependency while sanitizing replay anchors, so its behavior is relevant to the review. - **Evidence against:** The inspected runtime connects to a configurable LensMCP bridge and sends replay requests with credentials omitted., No concrete attack behavior was identified in the inspected source. ## Affected versions and remediation This report applies to @lensmcp/client-runtime@1.25.22. - Review the evidence and your use of @lensmcp/client-runtime@1.25.22 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.
