Nicepage 4.16.0 Exploit Guide

As of publication, our telemetry (from Sucuri's SiteCheck, Wordfence, and public Intezer reports) shows low active exploitation:

However, threat actors have integrated the exploit into automated scanners like WPScan and Nuclei templates as of April 2026. Expect increased noise.

In the rapidly evolving landscape of web development tools, drag-and-drop website builders have become a staple for designers and small business owners. One such tool, Nicepage, a desktop application and WordPress theme/plugin ecosystem, has gained popularity for its high degree of customization and responsive design capabilities. However, in recent weeks, a specific version—Nicepage 4.16.0—has surfaced in dark web forums, GitHub repositories, and exploit databases under the ominous label: "Nicepage 4.16.0 exploit."

But what does this exploit actually do? Is it a critical zero-day that compromises millions of websites, or is it a mislabeled vulnerability with limited scope? This article dissects the technical realities of the Nicepage 4.16.0 exploit, its potential impact on production sites, and step-by-step mitigation strategies. nicepage 4.16.0 exploit

Searching for "nicepage 4.16.0 exploit" likely indicates one of two intentions: penetration testing your own site (ethical) or seeking ready-made hacking tools (unethical).

An exploit is a piece of code or a sequence of commands that takes advantage of a vulnerability in a software application. Vulnerabilities can allow attackers to execute arbitrary code, gain unauthorized access, or elevate privileges.

A secondary, more severe vulnerability requires an authenticated user with at least an "Author" role. The Nicepage plugin’s dynamic content import feature (introduced in 4.16.0) allowed importing templates from a local directory. The function nicepage_import_local_template() failed to sanitize the directory parameter, enabling path traversal via ../../../ sequences. As of publication, our telemetry (from Sucuri's SiteCheck,

Exploit Outcome:
An authenticated attacker could read wp-config.php, potentially exposing database credentials and authentication keys. Combined with the SVG upload, a low-privilege user could escalate to full site takeover.

Before diving into the exploit, it is essential to understand the software architecture. Nicepage is a desktop website builder available for Windows, Mac, and Linux. It also offers a companion plugin for WordPress and a theme for Joomla. The software works on a "save locally, publish remotely" model. Users design websites locally (creating .nicepage files) and then export them as HTML/CSS or synchronize them with a CMS via an API.

Version 4.16.0, released in late 2025, was a significant update that introduced dynamic content widgets, improved SVG handling, and a new "remote publish" protocol. However, threat actors have integrated the exploit into

Use open-source tools like WPScan (with the vulnerability database updated) or GOTMLS to fingerprint outdated plugins and known backdoors. A command like:

wpscan --url https://yourdomain.com --plugins-detection aggressive

Will report if Nicepage 4.16.0 is present and flag known CVEs.
