AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection found a guarded global-install version bridge and product-aligned runtime operations, with no concrete attack behavior established. The static hints do not change that assessment.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

The postinstall hook runs for global npm installs; the bridge proceeds only for an adopted version store with a newer package version.

Impact

The inspected behavior did not establish credential theft, unconsented agent configuration changes, or other concrete attack impact.

Mechanism

The reviewed agent integrations handle session history, memory, requested backend operations, and CLI service setup.

AI rationale

Source inspection found a guarded global-install version bridge and product-aligned runtime operations, with no concrete attack behavior established. The static hints do not change that assessment.

Decision evidence

public snapshot

AI called this Clean at 90.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The postinstall hook runs only for global npm installs; its bridge skips packages without an adopted version store and only proceeds for a newer release.
The flagged agent paths are used for Codex and Claude session history or memory, and Copilot review output filters internal plan paths.
Inspected runtime code supports executable-path lookup, requested file and Git operations, backend session handling, and local session-file writes.
Service persistence is part of service setup, and the package exposes it through its CLI; no attack behavior was identified in the inspected paths.
The emergency-upgrade code names AgentLink release manifests at msclaude.ai.
