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

The cybersecurity world has been jolted by the discovery of a severe vulnerability, identified as CVE-2025-7697, that is making WordPress sites susceptible to a potential system compromise or data leakage. This vulnerability is associated with the WordPress plugin integration for Google Sheets and Contact Form 7, WPForms, Elementor, Ninja Forms. It primarily affects all versions up to, and including, 1.1.1. The severity of this vulnerability is significant due to the potential for unauthenticated attackers to inject<\/a> a PHP Object, thereby leading to system compromise or data leakage.<\/p>\n

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

CVE ID: CVE-2025-7697
\nSeverity: Critical (CVSS score: 9.8)
\nAttack Vector: Network (via PHP Object Injection<\/a>)
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, Data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

WordPress Plugin<\/a> Integration for Google Sheets and Contact Form 7, WPForms, Elementor, Ninja Forms | Up to and including 1.1.1<\/p>\n

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

The vulnerability lies in the verify_field_val() function of the affected plugin, which deserializes untrusted<\/a> input, making it susceptible to PHP Object Injection. Unauthenticated attackers can exploit this by sending a manipulated payload that allows them to inject<\/a> a PHP Object. Moreover, the presence of a POP (Property-Oriented Programming) chain in the Contact Form 7 plugin, often used alongside the vulnerable plugin<\/a>, amplifies the exploit. It allows the attackers to delete arbitrary files, causing a denial of service or executing remote code when the wp-config.php file<\/a> is deleted.<\/p>\n

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

The following conceptual example shows how an attacker might exploit<\/a> the vulnerability. This could be a sample HTTP request<\/a> containing a malicious payload:<\/p>\n

POST \/wp-content\/plugins\/vulnerable-plugin\/verify_field_val HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"malicious_payload\": \"<\/pre>\n
In this example, the \"malicious_payload\" would contain a serialized PHP object designed to exploit the PHP Object Injection vulnerability<\/a>.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users affected by this vulnerability<\/a> are strongly advised to apply the vendor patch immediately. If for any reason immediate patching is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. However, these should not be viewed as long-term solutions due to the high severity of the vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
