While there is no publicly documented major security exploit specifically labeled "Nicepage 4.16.0 exploit" in global vulnerability databases like CVE or NVD, Nicepage version
(released August 8, 2022) has been part of a lineage of versions that security researchers have flagged for specific path disclosure and file handling risks Nicepage.com Vulnerability Review: Nicepage (General Concerns)
Based on security community reports and official release notes, several areas of concern exist for users of older versions like 4.16.0: Sensitive Path Disclosure: Some security plugins, such as Hide My WP Ghost , have flagged the Nicepage WordPress plugin
for allowing potential attackers to see sensitive paths like in the source code. File Upload Risks:
Version 4.12 introduced "File Upload in Contact Forms". In early iterations of this feature, improper sanitization can lead to Remote Code Execution (RCE)
if an attacker successfully uploads a PHP script disguised as an image or document. Editor Plugin Credential Exposure:
Historical bug reports for the Nicepage Editor Plugin have noted issues where WordPress and Joomla password values were visible in the Property Panel. Outdated CMS Vulnerabilities:
Using a version from 2022 (v4.16.0) in 2026 significantly increases risk. Modern exploits often target legacy software that lacks current patches for Cross-Site Scripting (XSS) SQL Injection Version Context Release Date Key Change/Security Note
Introduced file upload functionality (potential RCE vector). August 2022
Added "Lock Elements" feature; no specific security patch noted. March 2026
Current version with Role-Based Access Levels and latest fixes. Recommendation
If you are still running version 4.16.0, your site is roughly four years behind the current security standard. You should manually update

The Nicepage 4.16.0 Security Update: Safeguarding Your CMS Integration For users of the
web design platform, version 4.16.0 marked a significant milestone—not just for its new design features, but for critical security improvements addressing long-standing concerns in the community.
While Nicepage is often praised for its ease of use, historical discussions have highlighted potential risks when integrating the Nicepage Editor Plugin with WordPress and Joomla. What was the issue?
Security audits of earlier versions, such as 4.12, revealed that sensitive information—including WordPress and Joomla password values
—could be inadvertently exposed within the Property Panel of the editor plugin. Furthermore, general vulnerabilities like CVE-2022-4160
affecting other WordPress plugins during the same period served as a reminder of how unescaped parameters can lead to SQL Injection and the leaking of sensitive database information. Key Fixes in Version 4.16.0 and Beyond
Nicepage 4.16.0, released in August 2022, focused on stabilizing the editor and introduced the "Lock Elements" feature. More importantly, it continued the vendor's efforts to patch "malfunctioning" elements that could potentially be leveraged by attackers, such as: Contact Form Vulnerabilities: Previous versions struggled with HTML code injection
within contact form submissions, which could be used to manipulate email content. Site Import Issues:
Fixes were applied to prevent malfunctions during site imports after changing site titles, reducing the surface area for unexpected script behavior. Plugin Hardening:
Addressing the exposure of admin credentials within the plugin interface. How to Stay Secure Security researchers emphasize that up to 92% of WordPress vulnerabilities
originate from third-party extensions rather than the core software. To keep your Nicepage-powered site safe: Update Immediately:
Ensure you are running the latest version. As of early 2026, Nicepage is on version 8.4. Follow WP Best Practices:
Use strong passwords, limit login attempts, and use reputable security plugins to protect core paths like Audit Your Forms:
