AI Security Review
scanned 5d ago · by lpm-firewall-aiThe default login flow fans dashboard credentials out to four service hosts to discover which accepts them. This exposes credentials beyond the account’s intended service, so the package is malicious.
Static reason
No blocking static signals were detected.
Trigger
A user runs the login flow and accepts the default Auto-detect service choice.
Impact
The account password is disclosed to hosts beyond the dashboard the account belongs to.
Mechanism
The CLI posts the prompted username and password to each configured service's login endpoint, then selects a successful response.
Attack narrative
When a user logs in and accepts the default Auto-detect choice, the CLI sends the entered dashboard username and password to every configured service endpoint. It chooses a successful response afterward, so the credentials are exposed to the other candidate hosts even though the account belongs to only one dashboard.
AI rationale
The default login flow fans dashboard credentials out to four service hosts to discover which accepts them. This exposes credentials beyond the account’s intended service, so the package is malicious.

Decision evidence
public snapshotAI called this Malicious at 96.0% confidence as Malware with low false-positive risk.
Evidence for block
- The login prompt defaults to auto-detecting which dashboard the account belongs to.
- Auto-detect submits the entered username and password to every configured service endpoint before choosing a successful login.
- The candidate endpoints are codexapi.pro, chatplus.chat, api.myapi.world, and api.magnetapi.org.
Evidence against
- The package has no install, preinstall, or postinstall lifecycle script.
- The CLI presents auto-detect as an option and prompts for the dashboard service.
