CVE-2024-5628: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in themefusion Avada (Fusion) Builder
The Avada | Website Builder For WordPress & eCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's fusion_button shortcode in all versions up to, and including, 3.11.9 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. NOTE: This vulnerability was partially fixed in 3.11.9. Additional hardening for alternate attack vectors was added to version 3.11.10.
AI Analysis
Technical Summary
The Avada (Fusion) Builder plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of user-supplied input in the fusion_button shortcode. Authenticated attackers with contributor-level privileges can inject arbitrary scripts that execute in the context of users visiting the affected pages. The issue affects all plugin versions up to and including 3.11.9. Partial remediation was introduced in 3.11.9, and additional protections were added in 3.11.10 to address alternate attack vectors.
Potential Impact
Successful exploitation allows an authenticated user with contributor or higher privileges to inject and execute arbitrary JavaScript in the browsers of users viewing the affected pages. This can lead to information disclosure and integrity impacts within the context of the affected site. The CVSS score of 6.4 reflects a medium severity with low complexity and no user interaction required beyond authentication.
Mitigation Recommendations
Users should upgrade to Avada (Fusion) Builder version 3.11.10 or later, where additional hardening against this vulnerability has been implemented. Since the vulnerability was only partially fixed in 3.11.9, relying on that version alone is insufficient. No official patch links were provided, but the vendor's versioning indicates 3.11.10 contains the full fix. Until upgrading, restrict contributor-level access to trusted users only.
