Released on , version 4.16.0 introduced helpful features like "Lock Elements" in the editor. While no major zero-day exploit has been publicly tied specifically to this version number, running software that is several years old is a known security risk.

The most concrete risk identified for Nicepage is its reliance on , a library known to contain vulnerabilities that could enable attacks like Cross-Site Scripting (XSS). Forum users have strongly criticized this as irresponsible, suggesting it exposes sites to preventable exploits. While the development team has previously defended using this "popular" version, they also stated a commitment to updating it in the future. The exact version in which jQuery was updated remains unconfirmed.

Older variations of Nicepage's contact form elements (specifically surrounding changes tracked up to version 4.12 and 4.16) allowed user-submitted fields to interact dynamically with local PHP mailer scripts. If an attacker bypasses client-side restrictions, they can pass malicious multi-part form data directly to the server. If the application fails to restrict executable extensions (like .php , .phtml , or .phar ), an unauthenticated attacker can upload a web shell, achieving immediate Remote Code Execution (RCE). 2.
