@pcb-dp/qa-commons@1.0.0
Authorized Test Package
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package automatically sends host and CI details to an unrelated external collector during installation. This is concrete install-time data exfiltration.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the postinstall script.
Impact
Unsolicited disclosure of local machine and CI environment details.
Mechanism
The script gathers hostname, home directory, platform, and CI provider, then POSTs the data to a fixed webhook.site endpoint.
Attack narrative
On installation, the postinstall hook runs index.cjs. It collects the machine hostname, home directory, platform, and a CI provider label, then sends those details in a POST request to a fixed webhook.site URL without installer consent.
AI rationale
The package automatically sends host and CI details to an unrelated external collector during installation. This is concrete install-time data exfiltration.
