What is CVE-2025-6740?

The Contact Form 7 Database Addon plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) through the 'tmpD' parameter. This vulnerability arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject malicious scripts into web pages.
