One potential source of confusion is the existence of CVE-2022-42710—a cross-site scripting (XSS) vulnerability that affects the system, which is an entirely different software product unrelated to Nicepage from Artisteer. Similarly, a separate SQL injection vulnerability exists in "nickpage.php" within phpCC 4.2 beta, which also bears no relation to Nicepage. These naming similarities do not constitute evidence of a vulnerability in Nicepage itself.
Forum records indicate that Nicepage 4.5.4 was actively used around March 2022, with users reporting compatibility and functionality issues when migrating projects between version 4.5.4 and newer builds (specifically version 4.6.4). This places version 4.5.4 in a transitional period of the software's development—neither the most recent release nor a legacy version deemed entirely obsolete.
Ensure that file permissions on your web server are strictly configured. Directories should generally be set to 755 and files to 644 . Prevent execution permissions in directories meant strictly for media uploads. 5. Reset All Credentials
Using unpatched backend engines or archaic jQuery footprints exposes deployed HTML pages to known Client-Side XSS vulnerabilities. If a site builder produces code containing vulnerable legacy snippets, attackers can manipulate DOM elements to target standard site traffic or administrative portal parameters. 2.

One reference that might be initially confusing is . This entry is for "niceforyou," a separate product, and is unrelated to Nicepage by Artisteer Limited. Similarly, while a CVE-2025-66470 exists for an XSS vulnerability, it is for the "NiceGUI" component of a different product, not Nicepage.

Before diving into potential threats, it is important to understand what Nicepage is. Developed by Artisteer Limited, Nicepage is a multi-platform website builder available as a desktop application for Windows and macOS, as well as plugins for popular content management systems like WordPress and Joomla. Its primary appeal lies in its revolutionary freehand positioning and drag-and-drop interface, which allows users to create responsive websites without writing any code. This "no-coding" approach makes it an attractive tool for individuals, designers, and small businesses looking for a simple solution to build visually appealing sites. The software in question, version 4.5.4, is an older build dating back to around early 2022.
While some of these instances could be false positives, triggered by the way Nicepage structures its assets or code, the repeated and widespread occurrence is a major red flag. It suggests that the code generated or the assets loaded by Nicepage may exhibit behavioral patterns commonly associated with malicious sites. For a site owner, this is a catastrophic outcome, as it makes their legitimate business appear as a threat to a significant portion of their potential visitors.
