Summary
Malicious code in pulse-pwn-9f3a2 (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (f8086e23ce4b6ff1ca043ca8d9c83f384455e0baee3d06cd79e8a0d5d52c04e1)

index.js contains top-level code that fetches /profile and sends document.cookie together with the response body to a hardcoded webhook.site URL (https://webhook.site/42c6d937-77c7-42a5-8678-ef06b4501e38) via a GET request with the cookie and profile content passed as URL-encoded query parameters. Any consumer that requires or imports this package in a browser-like context leaks the caller's session cookies and /profile response to an attacker-controlled collector. The destination is a third-party request-inspection service unrelated to any documented purpose of the package, and the exfiltration path fires on module load rather than through an explicit API call.
