The digital landscape is constantly evolving, and with it, the threats to our online presence. Website owners, especially those using content management systems like WordPress, must stay vigilant about potential vulnerabilities in their plugins and themes. Today, we’re shedding light on a security concern affecting the popular Parallax Image plugin for WordPress.
This plugin, designed to add visually appealing parallax scrolling effects to your website, was found to have a Stored Cross-Site Scripting (XSS) vulnerability. In simple terms, this means that an attacker could inject malicious code into your website through the plugin. Once injected, this code would execute whenever a visitor views the affected page, potentially leading to unauthorized actions, website defacement, or even stealing user session information.
The vulnerability specifically lies within the plugin’s dd-parallax shortcode. It failed to properly clean up (sanitize) user-provided input and escape output, creating a loophole for malicious scripts to be stored on your site. For an attack to occur, the perpetrator would need to be an authenticated user with at least contributor-level access to your WordPress site.

- Product: Parallax Image plugin for WordPress
- CVE ID: CVE-2024-9898
- Published Date: October 17, 2024

Affected Products
The Stored Cross-Site Scripting vulnerability impacts all versions of the Parallax Image plugin for WordPress up to, and including, version 1.8. If you are running any version within this range, your website may be at risk.
Current Status

Severity Level
Rated as Medium severity with a CVSS score of 6.4, this vulnerability poses a notable risk.

It underscores the importance of carefully managing user roles and permissions on your WordPress installation.
Possible Solutions
