AI Security Review
scanned 17d ago · by lpm-firewall-aiSource inspection found a conditional command-execution risk in the automatic update fallback: model-proposed commands are incompletely validated before Windows shell execution. The package has no install lifecycle hook, and the inspected behavior does not establish a concrete malicious payload, so a warning is appropriate.
Static reason
One or more suspicious static signals were detected.
Trigger
A user enters the REPL, an automatic update is attempted, and the standard update launch fails on Windows.
Impact
A response containing accepted shell syntax could run additional commands with the user's privileges.
Mechanism
The updater asks the configured model for a package-install command, applies a partial text filter, then passes the result to the command interpreter.
AI rationale
Source inspection found a conditional command-execution risk in the automatic update fallback: model-proposed commands are incompletely validated before Windows shell execution. The package has no install lifecycle hook, and the inspected behavior does not establish a concrete malicious payload, so a warning is appropriate.
Evidence
dist/main.jsdist/update-check.js
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest has no install lifecycle hook and lists matching-version first-party dependencies.
- The REPL starts automatic updates by default; setting its update option to false changes this to notification only.
- When an automatic update fails, the updater asks the configured model for an installation command using machine details and the error.
- The command check rejects selected dangerous words and requires a reference to this package, but does not reject shell operators.
- On Windows, the accepted model response is passed as a command string to the system command interpreter.
Evidence against
- The risky path requires a failed automatic update and a model response that passes the package-name check.
- The update feature is scoped to installing this CLI package; the inspected source does not establish a malicious payload or credential transfer.
