P4 Code coding agent server and command-line client

AI Security Review

scanned 2d ago · by lpm-firewall-ai

The inspected CLI and history-worker paths show product functionality, and the flagged shell and dynamic-function excerpts do not establish an attack. The unresolved runtime dependency sources prevent a clean determination.

Static reason

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

Trigger

Installing or using the package may activate dependency code that was not available for inspection.

Impact

The behavior of those dependencies cannot be assessed from the inspected source.

Mechanism

The manifest declares @cursor/sdk and playwright-core, but their source could not be reviewed in this snapshot.

AI rationale

Evidence

package.json

Decision evidence

public snapshot

AI called this Manual Review at 86.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json declares @cursor/sdk and playwright-core as runtime dependencies; their source was unresolved in this review snapshot.
The CLI entrypoint dispatches commands to the package’s CLI module.
The history worker is reached through a hidden CLI subcommand and accepts session-history operations.

Evidence against

The shell and dynamic-function matches occur in bundled agent-runtime support and a capability check; the inspected excerpts do not establish a reverse shell or credential transfer.
No concrete attack behavior was established in the inspected source.
