require-i18next @21.0.0

Summary

The package's preinstall.js reads a hex-encoded command string from preinstall.json, decodes it with Buffer.from(hex, 'hex'), and passes the result to child_process.exec during npm install . The decoded payload is a curl command that POSTs the installer's whoami, current working directory, hostname, and the contents of /etc/passwd to https://eousft8gflamm91.m.pipedream.net. The name resembles the legitimate i18next ecosystem but the package's only observed behavior is install-time data exfiltration to an attacker-controlled Pipedream webhook, with the payload obfuscated as hex in a sibling JSON file to evade inspection of the JS.
