What is CVE-2019-15838?

The Custom-404-Pro plugin for WordPress, prior to version 3.2.8, is susceptible to reflected Cross-Site Scripting (XSS). This vulnerability arises when user-controlled input is reflected in the server's response without proper validation or sanitization. A successful exploitation may enable attackers to execute arbitrary scripts in the context of the user's browser, potentially leading to data theft or session hijacking. It is crucial for users to update to the latest version to mitigate the risk.
