There are no widely documented public exploits or specific Critical Vulnerabilities and Exposures (CVEs) officially assigned to Nicepage version 4.16.0.
While there are reports of general security concerns and vulnerabilities in related software, here is the context regarding Nicepage and similar version numbers: Nicepage Security Context
Version History: Nicepage version 4.16 was released on August 8, 2022. While later versions (like 4.17) introduced features such as easier form submission, there are no specific security bulletins for 4.16.0 that indicate a critical exploit like Remote Code Execution (RCE) or SQL injection.
Information Disclosure Concerns: Users of the Nicepage WordPress plugin have reported that certain security scanners flags the plugin for potentially exposing sensitive paths like /wp-admin, which could theoretically facilitate brute-force attacks. However, Nicepage support typically maintains that these paths are essential for functionality and should be protected through general WordPress security best practices. Related (Non-Nicepage) Vulnerabilities
It is common for users to confuse version numbers with other software. For example:
CKEditor 4.16.0: This popular web text editor has a documented Cross-Site Scripting (XSS) vulnerability (patched in 4.16.2).
SEO Panel 4.6.0: This software has a documented Remote Code Execution (RCE) exploit often appearing in vulnerability databases.
If you are concerned about the security of a Nicepage installation, it is highly recommended to update to the latest version via the Nicepage Release Notes to ensure all general bug fixes and stability improvements are applied. Security issue in Nicepage plugin.
While there is no record of a major publicized exploit specifically titled "Nicepage 4.16.0 exploit" as of April 2026, Nicepage version 4.16.0 was released on August 8, 2022, primarily focusing on new editor features such as element locking.
However, various security discussions and vulnerabilities have been associated with Nicepage around that era. A common concern noted by users was the plugin's tendency to allow sensitive paths like /wp-admin to be visible in source code, which security tools like Hide My WP Ghost flagged as a potential brute-force risk. Additionally, older versions of Nicepage (e.g., 4.12) had confirmed critical vulnerabilities, such as Arbitrary File Upload in contact forms, which were addressed in subsequent updates. Feature Overview: Nicepage 4.16.0 Context
If you are investigating or writing about security for this specific version, here are the key highlights and known concerns from that period: Release Date: August 8, 2022. Key Features in 4.16.0:
Lock Elements: Introduced a feature allowing users to lock elements within the editor to prevent accidental movement. If you suspect your site was compromised via the Nicepage 4
User Email in Profile: Added visibility for the account email in the user profile to help manage multiple accounts.
Stability Fixes: Resolved issues related to custom fonts, image publishing, and multi-language site loading. Security Concerns of that Era:
Sensitive Path Visibility: Some security scanners reported that Nicepage revealed administrative paths in the HTML source, potentially aiding brute-force attacks.
Legacy Library Risks: Nicepage has historically been criticized by users for using older versions of libraries, such as outdated jQuery, which may contain known vulnerabilities if not properly patched by the developers.
Malware Scares: Some users reported Trojan flags on generated JavaScript files; however, these were often identified as false positives by the community. Security Best Practices for Nicepage Users
To protect your site if you are running an older version like 4.16.0:
Update Immediately: Ensure you are running the latest version. Major fixes for file upload vulnerabilities and CSS export errors were implemented in versions following 4.12.
Audit Contact Forms: Early 4.x versions had issues with unvalidated file uploads in forms; always verify that form inputs are sanitized.
Hide Admin Paths: Use a security plugin like Hide My WP Ghost to obscure sensitive WordPress directories that Nicepage might inadvertently expose. Security issue in Nicepage plugin.
While there is no widely documented or officially recognized critical vulnerability specifically labeled "Nicepage 4.16.0 exploit" in major security databases, users often search for such terms due to perceived risks in outdated versions of web design software. In general, Nicepage has maintained a strong security record, but older versions like 4.16.0 lack the cumulative security patches and feature updates provided in current releases. Understanding Version 4.16.0 and Security
Released in 2022, version 4.16.0 was a significant update focusing on design flexibility, including improved grid layouts and responsiveness. However, using any software version that is several cycles behind the current release carries inherent risks:
Dependency Vulnerabilities: Nicepage frequently updates its underlying libraries. For instance, past discussions on the Nicepage Forum have addressed concerns regarding outdated jQuery versions (like v1.9.1) which contain known vulnerabilities like Cross-Site Scripting (XSS).
Path Exposure: Some security plugins have flagged older versions for allowing sensitive paths like /wp-admin to be visible in source code, which can be leveraged by attackers for reconnaissance.
Beta Features: Older versions introduced features like "File Upload in Contact Forms" in beta. Unpatched beta features in early versions can sometimes lead to arbitrary file upload vulnerabilities if not properly secured with the latest server-side validation. How to Protect Your Website
If you are still running Nicepage 4.16.0 or any older version, the most effective "exploit" mitigation is to modernize your installation.
Update Immediately: Download the latest version from the Nicepage Official Site. Modern versions include fixes for reported bugs and improved compatibility with the latest versions of PHP, WordPress, and Joomla.
Verify Code Exports: If using the desktop application, re-export and re-upload your site files to ensure all client-side scripts (like jQuery) are updated to secure versions.
Harden CMS Access: For WordPress or Joomla users, employ security plugins such as Hide My WP Ghost to obscure sensitive administrative paths that may be exposed by older page builder plugins.
Use Official Channels: If you suspect a specific vulnerability, report it or check for status updates on the Nicepage Questions Forum.

There is currently no official record of a confirmed "Nicepage 4.16.0 exploit" or specific CVE (Common Vulnerabilities and Exposures) associated with this version of the Nicepage website builder.
However, users and security researchers have raised general concerns regarding the security of Nicepage-generated sites, particularly concerning outdated libraries and sensitive path exposure. Known Security Concerns & Related Vulnerabilities
While a specific "4.16.0 exploit" is not documented, the following vulnerabilities often appear in discussions related to Nicepage versions:
Exposure of Sensitive Paths: Recent reports indicate that the Nicepage WordPress plugin may inadvertently expose sensitive paths like /wp-admin. Security tools such as Hide My WP Ghost flag this as a risk that could facilitate brute-force attacks.
Outdated Libraries: Nicepage has been criticized for using older versions of jQuery (v1.9.1), which contains several known security flaws. While the Nicepage team has stated these do not directly lead to "real security problems," modern security scans will continue to flag them as a high risk.
Contact Form File Uploads: Version 4.12 introduced file upload capabilities in contact forms. Unrestricted file upload is a common vector for Remote Code Execution (RCE) if malicious scripts (e.g., .php files) are not properly filtered by the server.
