Cross-Site Request Forgery Vulnerability in Custom Post Type Plugin for WordPress

CVE-2025-13142

What is CVE-2025-13142?

The Custom Post Type plugin for WordPress has a security flaw that allows unauthenticated attackers to delete custom post types through Cross-Site Request Forgery (CSRF). This vulnerability arises from inadequate nonce validation in the deletion functionality. An attacker can exploit this weakness by tricking an authenticated site administrator into clicking a malicious link, thereby executing the deletion action without authorization. It is crucial for website administrators to implement security measures to mitigate this vulnerability and protect their site from potential unauthorized modifications.
