CVE-2025-7696 in Integration for Pipedrive and Contact Form 7, WPForms, Elementor, Ninja Forms Plugin
Summary
by MITRE • 07/19/2025
The Integration for Pipedrive and Contact Form 7, WPForms, Elementor, Ninja Forms plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.2.3 via deserialization of untrusted input within the verify_field_val() function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain in the Contact Form 7 plugin, which is likely to be used alongside, allows attackers to delete arbitrary files, leading to a denial of service or remote code execution when the wp-config.php file is deleted.

The vulnerability identified as CVE-2025-7696 affects a popular suite of WordPress plugins including Integration for Pipedrive and Contact Form 7 WPForms Elementor Ninja Forms which are widely used for contact form management and CRM integration. This security flaw exists within the verify_field_val() function where the plugin performs deserialization of untrusted input without proper sanitization or validation. The issue represents a critical security weakness that allows unauthenticated attackers to inject malicious PHP objects into the application's execution flow, effectively bypassing normal security controls and potentially gaining unauthorized access to the WordPress installation.
The technical exploitation of this vulnerability leverages PHP object injection principles where attacker-controlled data is passed through the deserialization process, creating a chain of object instantiation that can be manipulated to execute arbitrary code. This particular vulnerability is classified under CWE-502 as "Deserialization of Untrusted Data" which is a well-documented weakness in web applications that handle serialized data from external sources. The vulnerability becomes particularly dangerous when combined with existing POP (Property of Point) chains that may be present in the Contact Form 7 plugin, which is commonly used alongside the vulnerable integration plugins. These POP chains enable attackers to construct a sequence of method calls that can be executed during the object deserialization process, amplifying the impact of the initial injection.
The operational impact of this vulnerability extends beyond simple data compromise to potentially enable complete system takeover through remote code execution capabilities. When attackers can leverage the object injection to delete critical files such as wp-config.php which contains database credentials and other essential configuration parameters, they can effectively disable the WordPress installation leading to denial of service conditions. This scenario creates a cascading effect where the application becomes unusable and potentially exposes sensitive data to unauthorized access. The vulnerability's potential for remote code execution through file deletion operations aligns with ATT&CK technique T1059.007 for "Command and Scripting Interpreter: PowerShell" and T1486 for "Data Encrypted for Ransom" when combined with the ability to delete core configuration files.
Organizations using these vulnerable plugins should immediately implement mitigations including updating to the latest plugin versions where available, implementing web application firewalls to filter suspicious deserialization attempts, and monitoring for unusual file deletion patterns in WordPress installations. Additionally, administrators should conduct thorough security audits of their WordPress environments to identify any potential exploitation attempts and ensure proper input validation is implemented at all levels of the application stack. The vulnerability demonstrates the critical importance of validating and sanitizing all user inputs, particularly those that may be processed through serialization mechanisms, and highlights the need for comprehensive security testing of plugin ecosystems that integrate multiple third-party components.
