P4 Code coding agent server and command-line client

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The inspected excerpts do not substantiate the scanner’s reverse-shell or credential-exfiltration claims: they show a local shell process, a connectivity check, and an MCP settings type. The large bundled runtime and incomplete behavior tracing leave material uncertainty, so manual review is appropriate.

Static reason

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

Trigger

Running the p4c CLI or activating the bundled worker.

Impact

No confirmed malicious impact; unresolved runtime behavior needs further review.

Mechanism

The inspected worker starts a local shell process; the reviewed code does not establish that it connects to an external operator or transfers credentials.

AI rationale

Evidence

dist/bin.mjsdist/claudeHistoryWorker-BvaF6m2o.mjsdist/runtime-DKclsP_7.mjs

Network endpoints1

1.1.1.1

Decision evidence

public snapshot

AI called this Manual Review at 67.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest exposes a CLI entry point and declares no lifecycle script.
The flagged worker starts a local Bash process with piped input and output; the inspected excerpt does not establish a reverse shell.
The worker uses a request to 1.1.1.1 as a connectivity check.
The agent-configuration hint in the runtime file is a type declaration for an MCP server settings key.

Evidence against

The package includes large bundled runtime files whose behavior and callers could not be fully resolved in this inspection.
