CVE-2025-7696

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.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Potential Mitigations

• Make fields transient to protect them from deserialization.
• An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
