Malicious code in 0ctf-chalweb (npm)
-= Per source details. Do not edit below this line.=-
The package's entire content (xss.js) is a 2-line cookie-stealing payload that creates an Image element pointing to https://collaborator.gbrls.workers.dev/ with base64-encoded document.cookie appended. This is a textbook XSS cookie exfiltration primitive targeting an attacker-controlled Cloudflare Workers endpoint. Regardless of whether this was published as a CTF artifact, any consumer who installs and bundles this package into a web app will exfiltrate end-users' cookies. There is no legitimate use case for publishing a cookie-exfil snippet to the public npm registry.
