AI Security Review

scanned 4d ago · by lpm-firewall-ai

Inspected source did not establish a concrete attack, and the flagged socket and history-worker behavior has package-aligned explanations. A clean disposition requires citations for 205 distinct paths, above the schema limit of 128, so this review remains unresolved.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

No malicious activation trigger was confirmed.

Impact

No confirmed attack impact was established; the remaining uncertainty prevents a clean disposition.

Mechanism

The inspected worker returns requested session data to its caller, and the inspected proxy is loopback-bound with local destinations rejected.

AI rationale

Decision evidence

public snapshot

AI called this Manual Review at 72.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest identifies a CLI entrypoint and dependencies; the inspected manifest has no install lifecycle hook.
The CLI dispatches ACP bridge commands explicitly and otherwise loads its main command implementation.
The history worker handles session-message retrieval or session forking and writes the result to standard output.
The history path loads records using a project key and session ID, then applies requested limits and offsets.
The inspected SOCKS proxy binds to 127.0.0.1 and refuses destinations that resolve to local addresses.
The matched server code sends an HTTP upgrade response and installs an upgrade handler, consistent with WebSocket server support.
The runtime target describes settings.mcpServers and settings.plugins entries in the imported .mcp.json shape.

Evidence against

The inspected agent-configuration excerpts do not resolve all callers or configuration effects.
