In one of the most significant security incidents on the WordPress platform this year, over 400,000 websites have been compromised due to a critical vulnerability in the Happy Addons for Elementor plugin. This popular addon, designed to enhance the Elementor page builder, was exploited by attackers, causing widespread damage to numerous sites.
Details of the Attack
The vulnerability, identified as CVE-2024-10538, affected all versions of the plugin up to and including version 3.12.5. The attackers exploited a Stored Cross-Site Scripting (Stored XSS) flaw in the before_label parameter of the Image Comparison widget.
How the Attack Worked
Due to insufficient input sanitization and output escaping, attackers with “Contributor” user-level access or higher were able to inject malicious scripts into targeted website pages. Once visitors accessed these compromised pages, the malicious scripts executed actions such as:
- Stealing sensitive user data, including browser cookies.
- Hijacking user sessions.
- Redirecting users to malicious websites.
The Widespread Impact on Websites
With more than 400,000 active installations, the impact of this vulnerability was massive. Many sites faced severe consequences, including:
- Loss of sensitive user data.
- Being flagged as unsafe by search engines, leading to a drop in search rankings.
- Reputational damage for brands associated with affected websites.
Fixing the Vulnerability After the Attack
After reports of widespread exploitation, the developers of Happy Addons released a patch in version 3.12.6 on November 5, 2024. This update addressed the vulnerability by improving input sanitization and output escaping mechanisms, ensuring future protection against similar attacks.
