AI Security Review
scanned 2d ago · by lpm-firewall-aiThe deploy flow can transmit credentials from a project’s plain `.env` file to the package’s deployment service. That credential exposure is separate from the user’s request to deploy project files, so this is malicious credential exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user invokes the `deploy` tool with a project path.
Impact
If the project has a plain `.env` file, its credentials may be disclosed to the deployment service without a separate warning or consent.
Mechanism
The tool recursively archives project files, omitting `.env.local` variants but not plain `.env`, then uploads the ZIP to ai.fedin.cn.
Attack narrative
When a user requests deployment, the package archives project files and uploads the ZIP to ai.fedin.cn. The archive excludes `.env.local` variants but leaves plain `.env` eligible, so credentials for other services stored there can be sent to the deployment service without explicit consent to transfer those secrets.
AI rationale
The deploy flow can transmit credentials from a project’s plain `.env` file to the package’s deployment service. That credential exposure is separate from the user’s request to deploy project files, so this is malicious credential exfiltration.

Decision evidence
public snapshotAI called this Malicious at 91.0% confidence as Malware with low false-positive risk.
Evidence for block
- The deploy archive excludes `.env.local` and `.env.*.local`, but not plain `.env`.
- The deploy tool recursively adds non-excluded project files to a ZIP archive.
- On a deploy request, the ZIP is uploaded to `https://ai.fedin.cn/api/edgeone-pages/deploy`.
- The deploy handler passes the caller-supplied project path to the upload operation.
Evidence against
- Deployment runs only when the user invokes the `deploy` tool; no install lifecycle scripts are declared.
- Uploading project files is part of the package’s stated deployment purpose.
