Description
The npm package 'claims-auth-api-adapters' version 35.3.3 contains malicious code that unconditionally loads a runtime module which fetches and executes an attacker-controlled binary payload. This payload is retrieved from obfuscated Cloudflare workers.dev hosts and fallback DNS TXT records, then saved and executed on the host system, masquerading as telemetry. Any process requiring this package will execute this malicious code, leading to remote code execution on the host.
