AI Security Review

scanned 3mo ago · by lpm-firewall-ai

No concrete malicious chain was found, but unattended self-update plus install-time MCP configuration migration is risky enough to warn. The postinstall guard prevents a publish block under the stated policy.

Static reason

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

Trigger

npm install in the package's managed staging layout; later AI Kit server startup

Impact

Existing AI Kit IDE configuration can be changed; a compromised future registry release could execute through automatic update.

Mechanism

managed MCP-config migration and automatic npm self-update

AI rationale

Evidence

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs a postinstall hook.
Postinstall imports CLI only in ~/.aikit version-staging installs.
CLI migrates version-pinned MCP IDE configs automatically.
Runtime updater fetches and installs newer npm releases.

Evidence against

Postinstall is a narrow managed-staging guard and otherwise exits.
Migration targets existing AI Kit entries, not arbitrary agent configs.
No credential harvesting or unrelated exfiltration found.
Registry network use is package update functionality.
