@lensmcp/vite-plugin@1.25.43
LensMCP Vite plugin — valtio alias, source transform, and browser event bridge.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package’s observability purpose explains browser event collection, but its default session replay can capture unmasked form values, including password fields. The inspected code sends recordings to the local bridge and does not show an unrelated external collector, so this warrants a warning rather than a publish block.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
A developer starts a Vite dev server with the plugin enabled; replay is enabled by default unless its setting disables it.
Impact
Sensitive text entered into page forms may be included in recordings and made available to the local LensMCP consumer.
Mechanism
The plugin injects an rrweb recorder into served pages, which streams recordings to the bridge over HTTP using the configured host and port.
AI rationale
The package’s observability purpose explains browser event collection, but its default session replay can capture unmasked form values, including password fields. The inspected code sends recordings to the local bridge and does not show an unrelated external collector, so this warrants a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The plugin injects the replay recorder into served pages when replay is enabled; its type documentation says session replay is on by default.
- When no replay option or environment override is set, replayEnabled falls back to the capture settings file and returns enabled if reading or parsing it fails.
- Replay defaults to maskAllInputs false, and the recorder sets password masking to false when maskAllInputs is off.
Evidence against
- The package has no lifecycle scripts; replay runs when the user adds the plugin to a Vite app.
- The README describes the plugin as an observability tool that streams browser events over a local WebSocket.
- The default bridge host is 127.0.0.1, and the served runtime includes a per-start token.
