4.5.4 Exploit — Nicepage

Inadequate sanitization of data passing through active contact blocks or custom script forms allows attackers to perform cross-site scripting. Threat actors can inject malicious JavaScript into database tables via open input fields. When administrative users view these submissions inside the Nicepage backend dashboard, the browser executes the script, potentially leading to session hijacking or unauthorized administrative changes. Technical Indicators of Compromise (IoCs)

It is highly likely that the version number is being confused with other software that had notable vulnerabilities in that specific release, most notably:

For websites currently running on Nicepage 4.5.4 or any older version, the following actions are strongly advised:

The forum thread generated significant discussion. One user, "devy6," directly accused Nicepage of enabling exploitation by including vulnerable code in production builds without warning to non-technical users:

Nicepage 4.5.4 is a popular website builder that was found to have a significant security vulnerability, specifically a Stored Cross-Site Scripting (XSS) The vulnerability is tracked as CVE-2022-29349 🛡️ Vulnerability Overview Vulnerability Type: Stored Cross-Site Scripting (XSS) CVE-2022-29349 Affected Version: Nicepage 4.5.4 (and potentially earlier) Critical / High Patched in later versions 🔍 Technical Analysis

If a website running Nicepage 4.5.4 is targeted and successfully exploited, the consequences can be severe: Technical Indicators of Compromise (IoCs) It is highly

Many older versions of Nicepage relied on legacy versions of jQuery (such as v1.9.1). These outdated libraries have known Cross-Site Scripting (XSS) vulnerabilities that can be exploited even if the core Nicepage code is secure.

Ensure all user-generated content is encoded before being rendered in the browser. This converts characters like into HTML entities ( ), preventing the browser from interpreting them as code. 4. Content Security Policy (CSP)

Historically, early versions of visual page builders bundled static iterations of frontend libraries like jQuery to guarantee drag-and-drop feature compatibility. Version tracking shows that historical iterations relied on older framework footprints. Primary Attack Vectors and Underlying Vulnerabilities

There is or specific CVE (Common Vulnerabilities and Exposures) matching that version number in major security databases like the CVE Program or Exploit Database .

: HTTP requests mimicking legitimate administrative actions.

Because the platform outputs production-ready code directly into CMS environments, legacy iterations often packaged outdated structural code blocks, dependencies, or form processing endpoints that remained unpatched if automated updates were neglected.
