AI Security Review

scanned 14d ago · by lpm-firewall-ai

The inspected source establishes ordinary native dependency repair and agent project setup/migration capabilities, but the available excerpts do not confirm a malicious chain. This is not enough to support the scanner's malicious label, though the source review is limited and does not establish benign behavior across all flagged files.

Static reason

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

Trigger

Package installation triggers the postinstall repair script; project configuration changes are associated with explicit setup, migration, and server commands.

Impact

No confirmed attack impact was identified.

Mechanism

The inspected excerpts identify native dependency repair and agent-project setup or migration behavior, without establishing credential theft, covert persistence, or a malicious payload execution chain.

AI rationale

Evidence

package.jsonscripts/fix-better-sqlite3.cjsdist/commands/init.jsdist/commands/migrate.jsdist/commands/setup.jsdist/core/PostUpdateMigrator.js

Decision evidence

public snapshot

AI called this Manual Review at 38.0% confidence as Unknown with medium false-positive risk.

AI review observations

`package.json` defines a `postinstall` hook that runs the better-sqlite3 repair script.
`scripts/fix-better-sqlite3.cjs` describes downloading a native prebuild and falling back to a source build; no concrete malicious behavior was established in the inspected portion.
The inspected agent integration locations are consistent with project initialization, migration, server setup, or test tooling.

Evidence against

`dist/core/PostUpdateMigrator.js` describes updating agent hooks and project files after an update, but the inspected excerpt did not establish an unconsented malicious mutation.
`dist/core/GitSync.js` describes machine-key git signing and multi-machine state synchronization; no backdoor behavior was established in the inspected portion.
