zxcvb90-utils-helper@1.0.1
AI Security Review
scanned 8d ago · by lpm-firewall-aiThe entrypoint performs an unconditional transfer of page content to a fixed external collector. This supports blocking the package for data exfiltration.
Static reason
No blocking static signals were detected.
Trigger
The entrypoint runs in an environment where fetch and document are available.
Impact
Page content may be disclosed to the collector without a consent check.
Mechanism
It URL-encodes and sends the first 4,000 characters of the document HTML to a hard-coded webhook.site URL.
Attack narrative
When the package entrypoint runs in a browser-compatible environment, it sends a portion of the current page HTML to a fixed external endpoint. The manifest identifies this file as the entrypoint; no consent guard appears in the send operation.
AI rationale
The entrypoint performs an unconditional transfer of page content to a fixed external collector. This supports blocking the package for data exfiltration.
