The vulnerability stems from insufficient input sanitization and output escaping within the plugin's 'advanced_iframe' shortcode, allowing authenticated users with at least contributor permissions to inject malicious scripts into web pages.


The Advanced iFrame plugin, a widely used tool for embedding iframes in WordPress sites, has been identified with a critical Stored XSS vulnerability in all iterations up to version 2023.10. This security flaw enables users with contributor-level access or higher to execute arbitrary web scripts, posing a risk to site integrity and user safety. The issue has been addressed in the latest patch, version 2024.0, making an immediate update essential for all users.

Detailed Overview:

This vulnerability was uncovered by the diligent efforts of researcher Webbernaut, who pinpointed the flaw in the 'advanced_iframe' shortcode. Stored XSS vulnerabilities like this are particularly concerning as they allow the persistent embedding of harmful scripts into web pages, which can then be executed whenever the page is accessed. Such attacks could compromise user data, manipulate site content, or redirect visitors to malicious sites, underscoring the criticality of this vulnerability. The plugin's developers have responded with a patch in version 2024.0, which rectifies the input validation and escaping mechanisms to prevent such attacks.

Advice for Users:

  • Immediate Action: All users of the Advanced iFrame plugin should immediately update to the patched version 2024.0 to mitigate the risk posed by this vulnerability.
  • Check for Signs of Vulnerability: Users should review their site for any unusual content changes or scripts, particularly in areas where the 'advanced_iframe' shortcode is used, as these could be indicative of exploitation.
  • Alternate Plugins: Given the serious nature of this vulnerability, users may also consider evaluating alternative iframe embedding solutions as an additional precautionary measure.
  • Stay Updated: This incident highlights the importance of regular updates as a cornerstone of website security. Users should ensure all WordPress themes and plugins are kept up-to-date to protect against known vulnerabilities.


The swift resolution of the Stored XSS vulnerability in the Advanced iFrame plugin by its developers serves as a vital reminder of the dynamic nature of web security. Regular software updates are not just routine maintenance; they are a critical defense against the evolving threat landscape. By ensuring that their sites run the latest version 2024.0 of the Advanced iFrame plugin, WordPress site owners can safeguard their digital assets against potential exploitation.


In the digital tapestry that constitutes the modern web, each plugin and tool weaves its thread, contributing to the rich, dynamic experience that defines our online interactions. However, when a vulnerability like CVE-2023-7069 is discovered in a widely used WordPress plugin such as "Advanced iFrame," it serves as a stark reminder of the delicate balance between functionality and security. This particular flaw not only highlights the need for constant vigilance but also underscores the potential consequences of neglecting regular website maintenance.

About the Plugin:

"Advanced iFrame" stands out as a pivotal WordPress plugin, enabling users to embed content from other websites within their own. With over 1.8 million downloads and active installations numbering around 60,000, its impact is far-reaching. The plugin's utility in integrating external content seamlessly makes it a favorite among site owners, but this popularity also magnifies the implications of any security vulnerabilities it may harbor.

Vulnerability Details:

CVE-2023-7069 exposes a critical Stored Cross-Site Scripting (XSS) vulnerability in versions of "Advanced iFrame" up to and including 2023.10. Identified by researcher Webbernaut, the issue arises from the plugin's failure to properly sanitize and escape user inputs within the 'advanced_iframe' shortcode. This oversight grants users with contributor-level permissions or higher the ability to inject harmful scripts into web pages, which are then executed whenever those pages are accessed.

Risks and Impacts:

The repercussions of such a vulnerability extend far beyond mere unauthorized webpage alterations. They encompass potential threats to site integrity, user data compromise, and the erosion of trust between site owners and their audience. In a scenario where malicious scripts are injected, the affected sites could unknowingly host phishing schemes, distribute malware, or even redirect visitors to nefarious destinations, thereby amplifying the vulnerability's severity.

Remediation Steps:

To mitigate the risks posed by CVE-2023-7069, the immediate update to version 2024.0 of the "Advanced iFrame" plugin is imperative. This version addresses the identified XSS vulnerability, reinstating a safer environment for both site owners and their visitors. Additionally, site administrators are encouraged to regularly review their websites for any signs of compromise, especially in areas where the 'advanced_iframe' shortcode is employed.

Historical Context:

It's noteworthy that "Advanced iFrame" has encountered security issues in the past, with two vulnerabilities reported since February 2022. This history not only highlights the plugin's susceptibility but also emphasizes the importance of ongoing scrutiny and updates in maintaining security.

In conclusion, the discovery and subsequent resolution of CVE-2023-7069 within the "Advanced iFrame" plugin underscore a critical axiom of digital stewardship: the imperative of staying abreast of security updates. For small business owners, whose endeavors increasingly rely on their digital presence, the task of routinely monitoring and updating their WordPress sites, although daunting, is indispensable.
