CVE-2024-5790: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in thehappymonster Happy Addons for Elementor
The Happy Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘url’ attribute within the plugin's Gradient Heading widget in all versions up to, and including, 3.11.1 due to insufficient input sanitization and output escaping. 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.
AI Analysis
Technical Summary
The Happy Addons for Elementor plugin suffers from a stored XSS vulnerability (CWE-79) in the 'url' attribute of its Gradient Heading widget. This flaw allows authenticated users with Contributor or higher privileges to inject arbitrary JavaScript code into pages. The vulnerability is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'url' attribute. When a user accesses a page containing the injected script, the malicious code executes in their browser context. This issue affects all plugin versions up to 3.11.1 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). No official patch or vendor advisory is provided in the input data.
Potential Impact
Successful exploitation allows an authenticated user with Contributor-level or higher privileges to inject persistent malicious scripts into pages. These scripts execute in the context of any user viewing the compromised page, potentially leading to data theft, session hijacking, or other client-side attacks. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known exploits in the wild as of the published date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the Gradient Heading widget if feasible. Monitor for updates from thehappymonster regarding patches or official mitigations.
