AI Security Review

scanned 2d ago · by lpm-firewall-ai

The manifest has no install hook, and the flagged credential flow relies on provider or environment OAuth configuration rather than a verified fixed publisher gateway. Static similarity and generic dynamic-code indicators do not establish malicious behavior.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A user invokes OAuth login after configuring a provider or OAuth endpoint.

Impact

No publisher-selected credential recipient or confirmed attack impact was established.

Mechanism

The application resolves OAuth endpoints from provider configuration or environment variables, completes login, and uses the returned token and base URL.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 83.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json exposes the desktop entry point and has no install lifecycle hook.
OAuth endpoints default to empty values and can be supplied through environment variables or provider configuration; login uses that resolved configuration.
OAuth login stores the returned token and uses the returned base URL; inspected source shows no fixed publisher gateway.
Flagged support files and the inspected dependency sources show ordinary library or plugin behavior; no concrete attack behavior was established.

Evidence against

Static hints allege a credential redirect, but inspected source does not substantiate a fixed unofficial gateway.
