Nicepage — 4.16.0 Exploit !!top!!

As discussed in security audits across plugin environments on the Nicepage Support Forum , older instances of Nicepage are prone to exposing critical back-end pathways (such as /wp-admin hooks or exact server file locations) directly inside public-facing theme source code. This footprint allows attackers to perform precise directory brute-forcing and target known underlying exploits in the hosting environment. Technical Breakdown of an RCE Exploitation Workflow

The exploit affects websites that meet all of the following criteria:

Resolved issues related to custom fonts, image publishing, and multi-language site loading. Security Concerns of that Era:

To protect your site from any potential , follow these essential security steps: A. Update the Nicepage Plugin

The single most effective defense against this vulnerability is to upgrade the Nicepage plugin or standalone application to the latest secure version. The developers have patched the authorization and input validation gaps in subsequent releases. As discussed in security audits across plugin environments

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

: Attackers scan websites using automated dorks or signature tools like wpscan to locate specific directories containing /wp-content/plugins/nicepage/ or identify specific generator tags referencing version 4.16.0 .

Given the nature of website builders, adopting robust security practices is essential:

I couldn't find publicly available PoC or exploit code for this specific vulnerability. However, I can provide a hypothetical example of how an attacker might craft a malicious request: Security Concerns of that Era: To protect your

Security monitoring platforms have tracked 441 different Nicepage versions in the wild, from early releases up to the latest version 7.2.3. Across this extensive catalog, the number of versions marked as "vulnerable" is zero. This is notable because many competing site builders and content management systems regularly report vulnerabilities with CVSS scores and published exploit code.

Our team contacted Nicepage support on February 15, 2026. Initially, they classified the reports as "low severity" because the exploit requires authenticated access for the path traversal. However, after public disclosure by security researcher Jeremy Trinka on March 1, 2026, Nicepage released version with the following fixes:
