lasha-ctf-poc@1.0.0
AI Security Review
scanned 10d ago · by lpm-firewall-aiThe manifest points to code that actively transmits browser cookie data without a consent check. This is concrete credential exposure, so the package should be blocked.
Static reason
No blocking static signals were detected.
Trigger
Loading index.js in a browser context where fetch and document are available.
Impact
Cookies accessible to the script, potentially including session credentials, are disclosed to the endpoint.
Mechanism
The code serializes document.cookie into a JSON field and POSTs it to /addPost.
Attack narrative
When the entrypoint runs in a browser context, it reads document.cookie and sends the value in a POST request to the current origin's /addPost route. Cookies available to script may include session credentials.
AI rationale
The manifest points to code that actively transmits browser cookie data without a consent check. This is concrete credential exposure, so the package should be blocked.
