Critical WordPress Plugin Flaw Puts 70,000+ Sites at Risk of RCE

A critical security vulnerability has been discovered in the popular WordPress plugin “Database for Contact Form 7, WPforms, Elementor forms,” affecting all versions up to 1.4.3.

The vulnerability, assigned CVE-2025-7384 with a CVSS score of 9.8, enables unauthenticated attackers to inject malicious PHP objects and potentially delete arbitrary files from affected websites.

Technical Analysis of PHP Object Injection Flaw

The vulnerability stems from the deserialization of untrusted data in the plugin’s get_lead_detail function.

This flaw allows attackers to perform PHP Object Injection without authentication, exploiting the unsafe handling of serialized data.

The vulnerable code processes user input through deserialization operations without proper validation, creating an entry point for malicious payloads.

php// Vulnerable code pattern in get_lead_detail function
$data = unserialize($_POST['serialized_data']); // Unsafe deserialization

When combined with a Property-Oriented Programming (POP) chain present in the Contact Form 7 plugin, which is commonly installed alongside the vulnerable plugin, attackers can escalate the object injection to achieve arbitrary file deletion.

This exploitation chain can lead to denial of service (DoS) conditions or even remote code execution (RCE) when critical files like wp-config.php are deleted.

Impact Assessment and Remediation Strategy

The vulnerability poses severe risks to WordPress installations, particularly those using Contact Form 7 in conjunction with the affected database plugin.

Successful exploitation can result in complete website compromise, as attackers can target essential configuration files and potentially gain administrative access.

Vulnerability Details Summary:

Attribute	Details
CVE ID	CVE-2025-7384
CVSS Score	9.8 (Critical)
Attack Vector	Network (AV:N)
Authentication Required	None (PR:N)
Affected Versions	≤ 1.4.3
Patched Version	1.4.4
Plugin Slug	contact-form-entries

The vulnerability was publicly disclosed on August 12, 2025, and a patch was released shortly after.

Website administrators should immediately update to version 1.4.4 or newer to prevent exploitation. Security researcher Mikemyers identified and reported this critical flaw through responsible disclosure.

Given the unauthenticated nature of this vulnerability and its potential for remote code execution, organizations using affected versions should prioritize immediate patching and consider implementing additional security measures such as Web Application Firewalls (WAF) and regular security monitoring to detect potential exploitation attempts.
