Technical Details for CVE-2025-0291

Vulnerability Analysis

The vulnerability is categorized as a type confusion issue within the V8 engine of Google Chrome. This bug can be exploited by leveraging incorrect type casting, allowing potential attackers to achieve remote code execution within a sandboxed environment.

function exploit() {
    let crafted = // Malicious object creation leads to type confusion
        "<script>...exploit logic...</script>";
    document.write(crafted);
}
