Overview<\/strong><\/p>\n

The CVE-2025-7384 vulnerability is a critical security flaw affecting the Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress. This prevalent plugin, used on many WordPress websites for contact forms, is susceptible to a PHP Object Injection attack. The vulnerability lies in the deserialization<\/a> of untrusted input in the get_lead_detail function. This security flaw is of utmost importance due to the widespread use of WordPress and the mentioned plugins, putting a vast number of websites at risk of system compromise<\/a> or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-7384
\nSeverity: Critical (CVSS: 9.8)
\nAttack Vector: Unauthenticated network<\/a>
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Database for Contact Form<\/a> 7, WPforms, Elementor plugin | All versions up to and including 1.4.3<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability exists due<\/a> to a lack of proper sanitization of user input in the get_lead_detail function. This allows an unauthenticated attacker to inject a PHP Object into the plugin’s code<\/a>. Given the additional presence of a POP (Property-Oriented Programming) chain in the Contact Form 7 plugin, an attacker can manipulate the execution path of the application, leading to arbitrary<\/a> file deletion. This can result in a denial of service or remote code execution<\/a> when the wp-config.php file, which is crucial for WordPress operation, is deleted.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how an attacker might exploit this vulnerability, using a malicious HTTP POST request:<\/p>\n

POST \/wp-json\/contact-form-7\/v1\/contact-forms\/123\/feedback HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"your-name\": \"John Doe\",\n\"your-email\": \"john.doe@example.com\",\n\"your-subject\": \"Hello\",\n\"your-message\": \"a:1:{i:0;O:8:\\\"stdClass\\\":1:{s:4:\\\"file\\\";s:15:\\\"\/wp-config.php\\\";}}\"\n}<\/code><\/pre>\n
In the above example, the ‘your-message’ field contains a serialized PHP object designed to delete the wp-config.php file<\/a>.<\/p>\n
Mitigation<\/strong><\/p>\n
Users are urged to apply the vendor patch immediately once available. In the interim, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation. Regularly updating and patching systems, employing least privilege principles, and implementing robust input validation can help prevent such vulnerabilities<\/a> in the future.<\/p>\n","protected":false},"excerpt":{"rendered":"
